treeview: Ensure search popover is properly inserted

Browse Source 
The css tree and the widget tree are not in sync, so we need
to explicitly set the parent of the css node before inserting
the widget, or else we end up with critical warnings and a
non-working popover.

This can be seen in the print dialog, when moving the focus
to the printer list.
