[CollapsingToolbarLayout] White Flash During Collapse Animation

[royaff0]

Description: When a CollapsingToolbarLayout collapses, a brief white flash is visible. This flicker appears to be synchronized with the scrimAnimationDuration. It occurs just before the contentScrim and statusBarScrim colors are fully shown.

Expected behavior: The contentScrim and statusBarScrim should fade in smoothly
