fix(previews): preview doesn't work as expected when Faust configured #233
Description
When Faust enabled and "Front-end site URL" entered in the settings, it overrides the default behavior of HWP Previews.
NOTE: Removing "Front-end site URL" from Faust settings seems to fix this issue
This is what you get by clicking the preview button with the config below:
- Faust enabled, front-end URL set
Expected:
Should've opened default WordPress preview template with an iframe, showing frontend
Observed:
It redirects to the frontend URL defined in Faust settings, with different parameters than specified in HWP previews
This is for redirected previews in HWP Previews:
- Faust enabled, front-end URL set
Expected:
Should've redirected to the URL specified in HWP previews plugin
Observed:
Redirects to the domain specified in HWP Previews plugin, without respecting the parameters

Redirected previews conflict will be fixed with #240. iframe conflict however is a bit complicated. Faust provides a filter to disable frontend redirects for the specific URLs, but those URLs have to be exact match. Thus all the preview URLs have to be supplied to that filter to disable redirects as far as I understand.
On the other hand, and more importantly we don't want to suppress the redirect feature of Faust (an independent plugin) for an optional feature (iframe) of HWP Previews. Instead I'll document this conflict in #229 and provide an instruction on how to resolve this conflict, by removing frontend_url from Faust.

Thanks for so much context here. I think that sounds like a good approach. We might consider at some point in a breaking change to remove previews from Faust too which I guess would solve this issue too?

@colinmurphy we already remove the previews link replacement functionality of Faust by enabling the HWP Previews with #240. The iframe issue here is related to "redirect all to frontend" feature of Faust which is not connected to the previews. That's why I think we shouldn't do anything about it. If users want to use iframe with Faust, they can disable the redirect functionality by removing frontend url from the settings, and I'll document this fix.

Wouldn't removing the front-end URL from Faust config also break link rewrites? Not sure that's a viable fix for this issue.
