Fix bubbles being empty

Bubbles updates the bounds and visibility a bunch which resulted
in multiple pending transactions and the visibility one would get
clobbered resulting in an empty bubbles view.

This CL tracks the state of visibility & bounds in TaskViewTransitions
then if there's a bounds / visibility change that already matches
the state we can skip it.

Test: atest TaskViewTest TaskViewTranstionsTest
Test: manual - open a bubble, collapse it, open it again
               => verify the contents is visible
             - add multiple bubbles, select one, drag it to dismiss
               => verify that the next bubble contents is visible
             - open a bubble, switch to the overflow, switch back
               to the bubble
               => verify that the bubbles contents is visible
