Slightly optimize the iterator-based method for finding popovers
Slightly optimize the iterator-based method for finding popovers

As we already bounds-check the widgets in our map iterator, we have
access to the associated popover. Instead of returning the parent widget
and then doing another lookup, we just return the popover we already
know to be valid.
