popover: Update scrollable on relative-to hierarchy changes

Browse Source 
The relative-to widget may be reparented itself into/out of a
scrollable. In this cases make the hierachy-changed handler to
unset the parent scrollable when unparented, and look up again
the parent scrollable after it's reparented.
