Example:
- Create a simple component A containing a shape with an image fill
- Create a component B with several instances of component A in it
- In component B, override the image fills of the component A instances
- Publish the file as a library and create an instance of component B in another file
Result: The image fills that have been overridden are blank in the second file (even though they are properly displayed in the asset browser).
This might be the same issue as Resolved: Overrides not preserved when library is pushed, but that solution does NOT work (“Fix instance overrides” does nothing).
