Fixes #1143.

This keeps the existing focus-after-render behavior for the initial step render, but skips the delayed step.el.focus() on later Floating UI auto-update/reposition calls. That prevents mobile viewport/keyboard resize updates from stealing focus back from an input attached to the active step.

The regression test covers the focus behavior directly: the step element is focused once after initial render, then a focused input remains focused after a later reposition update.

Checks run:

  • CYPRESS_INSTALL_BINARY=0 npx pnpm install --lockfile=false
  • npx pnpm -F shepherd.js exec vitest run test/unit/utils/floating-ui.spec.js
  • npx pnpm -F shepherd.js test:unit:ci
  • npx pnpm -F shepherd.js lint:js
  • npx pnpm -F shepherd.js lint:prettier
  • npx pnpm -F shepherd.js types:check
  • npx pnpm -F shepherd.js build
  • git diff --check

Notes:

  • CYPRESS_INSTALL_BINARY=0 npx pnpm install --frozen-lockfile is currently blocked by a duplicate @vitest/pretty-format@4.1.5 mapping in pnpm-lock.yaml.
  • Cypress browser tests were not run.

📝 Walkthrough

Walkthrough

Tooltip positioning now uses Floating UI’s computed strategy for non-centered tooltips, preserves fixed positioning for centered tooltips, avoids duplicate arrow middleware, and focuses each tooltip step only after its first positioning update.

Changes

Tooltip positioning and focus behavior

Layer / File(s) Summary
Initial focus and positioning flow
shepherd.js/src/utils/floating-ui.ts
Limits delayed focus to the first positioning update and uses the computed positioning strategy for non-centered tooltips.
Middleware composition
shepherd.js/src/utils/floating-ui.ts
Merges user middleware before Shepherd’s arrow middleware and skips duplicate arrow middleware.
Positioning and focus validation
shepherd.js/test/unit/utils/floating-ui.spec.js
Adds mocked Floating UI positioning, DOM fixtures, timer handling, and tests for middleware, positioning, and one-time focus behavior.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 12f20

Custom arrow middleware can leave tooltips mispositioned or fail to position the configured arrow element, affecting consumers that customize tooltip arrows. Merge should wait for this bounded positioning issue to be resolved or explicitly accepted.

Clarify the rationale for pinning eslint-plugin-cypress to version 5.3.0.

This change pins eslint-plugin-cypress to exactly 5.3.0, removing the caret range (^) used by other dev dependencies. While version 5.3.0 has no known security advisories, it is 2 major versions behind the current release (6.4.1). If this pin is intentional—such as to resolve the pnpm install conflicts mentioned in the PR summary—document the reason in the commit message or add a comment explaining why this package uses a different versioning strategy than peers.

Thanks for this, @serendipitous-syntax, and sorry it sat unreviewed for three months. I dug into it properly — the core change is correct, and I want to lay out what I verified plus the two things standing between it and a merge.

The fix is right, and I checked the part I was most worried about

My concern going in was scope: if shouldFocusAfterRender were module-scoped, only the first step of a tour would ever receive focus and every subsequent step would silently lose keyboard and screen-reader users — worse than the bug being fixed.

It isn't. let shouldFocusAfterRender = true is a function-local in setupTooltip, captured by the autoUpdate closure, and setupTooltip has exactly one call site: Step._setupElements(), which _show() calls on every show after _teardownElements() nulls this.el. New element, new closure, flag back to true. So it's per-step-show, not per-tour.

Verified rather than assumed, in real headless Chrome against a three-step tour:

step1 -> DIALOG.shepherd-element[step=s1]
step2 -> DIALOG.shepherd-element[step=s2]
step3 -> DIALOG.shepherd-element[step=s3]
back() -> DIALOG.shepherd-element[step=s2]
hide()+show() -> DIALOG.shepherd-element[step=s2]
tour A complete, tour B start -> DIALOG.shepherd-element[x1]   (no cross-tour leak)

All 11 existing a11y.cy.js tests pass, and a probe confirming a post-first-render viewport resize no longer steals focus also passes. Applying just your floating-ui.ts onto current main: 225 unit tests green, eslint clean, types:check clean.

Blocker 1: the eslint-plugin-cypress pin breaks CI

Commit 2a23169 pins eslint-plugin-cypress to 5.3.0 in shepherd.js/package.json, but pnpm-lock.yaml still records ^5.3.0. .github/workflows/test.yml runs a bare pnpm install, and pnpm defaults to --frozen-lockfile when CI=true — so this fails with ERR_PNPM_OUTDATED_LOCKFILE at the install step of all three jobs, turning a one-job failure into a three-job failure.

It also isn't needed: eslint . exits 0 on current main with your source change and no pin. And it's the sole cause of the current merge conflict — floating-ui.ts merges cleanly.

Worth knowing: the frozen-install failure you hit (duplicate @vitest/pretty-format@4.1.5) was real at your branch point but is already gone on main, so a rebase clears it without the pin.

Could you drop that commit and rebase onto main, keeping only 63b7bef?

Blocker 2: CI has never actually run on this branch

actions/runs?head_sha=2a23169 returns total_count: 0. The green-looking checks are CodeRabbit plus a qlty run that reports "Skipping analysis of pull request from a fork". The one real run was against your first commit and failed lint for a reason whose logs have since expired. So there's no CI evidence either way yet — the rebase should fix that.

One request before merge

The regression test doesn't guard the invariant it exists to protect. I hoisted shouldFocusAfterRender to module scope — exactly the refactor that should trip it — and the spec still passed 7/7, while focus broke on every step from 2 onward and on every subsequent tour. The Cypress suite misses it too; a11y.cy.js only asserts focus at tour start.

Could you add a case that calls setupTooltip twice with a fresh element the second time (simulating step 2 / tour.back()) and asserts focus fires once per call? That's the thing a future refactor would break.

Optional, not blocking

  • Consider clearing the flag only once focus actually lands (checking document.activeElement === step.el in the final .then). main got an implicit retry for free from repositioning; there's now exactly one attempt per show. I couldn't construct a case where the single attempt fails, so this is hardening rather than a defect.
  • A named parameter instead of the 5th positional boolean on setPosition, plus a comment noting the flag is per-step-show — that's the one non-obvious fact a future reader will get wrong.

For anyone finding this later: this fixes #1143. It does not close #2117 (still no autoFocus: false opt-out — first-render focus is preserved by design) and it neither fixes nor breaks #1793.

Nice piece of debugging — the diagnosis in the original 2020 thread was right and this is the correct mechanism for it.

258-274: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Support user-provided arrow middleware end to end.

When arrow() runs before offset(), the final tooltip position changes after middlewareData.arrow is calculated. Move the selected user arrow middleware after coordinate-changing middleware. Apply the coordinates to its configured element, or retain Shepherd’s arrow middleware when custom rendering is unsupported.

Update shepherd.js/test/unit/utils/floating-ui.spec.js to expect arrow after offset() and assert positioning on the configured arrow element.
