Import and expose do not respect private imports

Import and expose do not respect private imports

I am working with model with the following structure

package Model {
  package a {
    part p;
  }
  package b {
    private import a::*;
  }
  package c {
    view v {
      expose b::**;
    }
  }
}

Using pilot implementation rendering the view actually exposes part p, whereas I am expecting nothing.

I actually made tests with slightly more complex example, but structure is the same:

package Model {
    private import SysML::*;
    private import StandardViewDefinitions::**;
    part def Component;
    package Parts {
        private import Model::*;
        part 'System A' {
            part 'Part A1' : Component;
            part 'Part A2' : Component;
        }
        part 'System B' {
            part 'Part B1' : Component;
            part 'Part B2' : Component;
        }
    }
    view partTree : BrowserView {
        expose Model::Parts::*;
        filter @PartUsage;
    }
}

Using it, the following figure is rendered:

Notice partTree view object that is present on the diagram. It gets exposed because it gets imported into exposed Model::Parts package by line private import Model::*, but I expect that import to remain private to Parts package and thus not exposed by view.

That looks like a bug to me.
