This change addresses an issue where touching the bottom of the screen would result in the dismissal of the multi instance menu, but leave the taskbar in a state that it would not auto stash. This is because the view was being removed through another way leading to taskbar being in a bad state. Now when the view is removed, the taskbar is correctly reset.
Fix: 380304394
Bug: 315989246
Test: Manually launch the menu then tap the bottom of the screen. Ensure that taskbar eventually auto stashes.
Flag: com.android.launcher3.enable_multi_instance_menu_taskbar
