System bar color changes suddenly when swiping open the up next queue

When swiping open the up next queue, the system bar at the top of the screen suddenly changes color. It would be nice if there was a smoother transition here as you swipe open the up next view.

##### Pixel 3, Android 12, Pocket Casts 7.20 pre-release build

Start by reproducing the issue on a Pixel 3 running Android 12 while swiping open the up next queue, using the linked recording as the reference. Trace the up next view and system bar transition; done means the bar changes smoothly during the swipe rather than suddenly changing color.
