Interrupt the animation when the user swipes home.
When there are no bubbles the stashed state now keeps getting
updated so that when a bubble is created we can correctly
detect stash change events.
Flag: com.android.wm.shell.enable_bubble_bar
Fixes: 378967270
Test: manual
- dismiss bubble bar
- launch app
- send bubble
- swipe home during the animation
- observe the bar does not stash at the end
