the layout size hints can change all together, in any order possible.
the only way to have a deterministic behavior is to compress them
and do the sync of the size all at once.
also being sure to do a single adjustGeometry (one X call) instead of
separate setWidth/setHeight
a test for the issue is dialog_resizeWithParent.qml
