The content shines through below the stickyActionBar during transition

Bug report

Describe the bug
Because the stickyActionBar is crossfaded, the content shines through below it, just watch the video.

RPReplay_Final1725576600.mov

Steps to reproduce

Steps to reproduce the behavior:

1. Add a stickyActionBar with a solid color background
2. Do a multi step modal and transition to the next screen

Expected behavior

If the stickyActionBar has a solid background, it should be respected and the transition should be "clipped" because of it.

Additional context

Why is the stickyActionBar being crossfaded? Wouldn't it be enough to keep the old stickyActionBar fully in place, fade the new stickyActionBar in and remove the old stickyActionBar afterwards? That way the transparency wouldn't shine through.
