Prevent resize animation from changing the requested visibilities

The insets resize animation is used to produce the callbacks of the
animation progress to the app. It shouldn't change the state of the
insets controller.

Fix: 205082601
Test: 1. Open a sticky-immersive app on a device which has taskbar.
      2. Make sure taskbar is minimized on apps.
      3. Swipe from bottom twice to go to home screen.
      4. Open the same app again and see if task bar is hidden.
