Sorry I am confused then as to what the text "This does mean that a
tooltip's parent can never change, and a popup's parent can never change".
I think I misread it as "if we use xdg_surface set_parent, you cannot
change the parent", thus implying that xdg_surface set_parent cannot change
it. I think what you actually meant was "the current scheme does not allow
you to change the parent, this proposal *does* allow the parent to change".

If there are problems with making the grabs work, I think it is ok if
attempting to change the parent is either an error or ignored for surfaces
with the popup role.
