[sticky] Clear propagated sticky constraints from foreignObjects

By default foreignObjects create a PLSA. This can be turned off by
setting overflow:visible.

We had an issue upon a dynamic change when the sticky-constraints would
be invalid upon this dynamic change. Clear them when this happens.

(note there is a bit of spec vaugeness here, e.g. for position:fixed,
position:absolute we don't let them propagate past foreignObject
boundaries. Previously - before the new logic - we let them, now we
don't - which is consistent with fixedpos / abspos).
