conradchen dac9bf360a [M3][Color] Set android:windowBackground to android:colorBackground
The same remapping is done on API 21+ by framework base themes. On API levels lower than 21, AppCompat base themes "backport" the behavior to map window background to a separate color resources. With Material 3 we want a consistent and clear behavior, this CL explicitly remaps android:windowBackground to android:colorBackground so the behavior will be the same across all API levels.
