Retainer box set to Render on invalidation doesn't draw when inside SCommonAnimatedWidgetSwitcher

When a retainer box that’s set to render on invalidation - without render on phase - with a widget inside is placed inside of an SCommonAnimatedWidgetSwitcher, the retainer box doesn’t update the opacity / tint of the retained content when animating, thus making the contents appear blank. The content does however reappear if the retainer is inside of a scrollbox, and that box is scrolled.

See the attached video and project for the issue.

Also, below are some screenshots of the setup:

This issue seems to be resolved after integrating pull request #14932 , that’s created for [Content removed] issue - however i am not sure of the side effects of this issue.

Hi,

We’ve reviewed and integrated the linked PR, as it looks like the right approach for resolving a few retainer panel issues we’ve seen in the past. You can cherrypick that change at CL#55750580 if you haven’t already integrated it directly.

Best,

Cody
