When an embedded activity is entering PIP when it is the only activity in the Task, the whole Task will enter PIP. When this happens, we want to reset all organizer override config so that the activity will get the correct config. We don't want to remove the TaskFragment because we can use it to get the windowing mode change in organizer. Besides that, we will disallow any further organizer override to the TaskFragment in PIP.
