Fix jank when rotating an expanded bubble

Previously we were removing all views and re-expanding the bubble after orientation changes.
That behavior also made the TaskView invisible and then visible again which triggered a SEND_TO_BACK followed by a
SEND_TO_FRONT shell transitions which caused flickering and noticeable latency before the task reappears.

This CL updates the positions and dimensions of the views without removing and readding them.
