textview: Ensure popup menu is properly inserted

Browse Source 
In the presence of attached children, 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
menu.

This can be seen in testtextview.
