Revert^2 "Store bubble bar state in sysui proxy"

This reverts commit fbfec0d3e1.

Reason for revert: Per the comment in the bug, this test was still failing after the rollback: https://b.corp.google.com/issues/413593389#comment7. The real culprit was a flag which was rolled back here: https://b.corp.google.com/issues/413593389#comment10.
