Pinning or unpinning a persistent widget, such as Jitsi, could cause the
PiP view and the app drawer to fight for control over the widget, since
the PiP view never realized that it was supposed to relinquish control.
This was due to a race between the WidgetLayoutStore update and the
AppTile lifecycle tracking update.
