Cling allows touch explore and accessibility focus search behind it.

1. Touch exploration is performed through hover events and
   the cling has to consume them to prevent touch exploring
   content behind it to achieve modal window like behavior.

2. Since the cling should behave as a modal window, the
   accessibility focus search should not returning items
   behind the cling, so the focus search should use the
   cling as its root.
