==================== Summary ====================
Name: Morphic-mt.1716 Author: mt Time: 12 January 2021, 2:52:47.977356 pm UUID: 93f95f53-4457-5e4c-a157-5cbf89aa7328 Ancestors: Morphic-mt.1715
Fixes a bug in resize grips (having #rigid targets) that are placed within layouted (usually #shrinkWrap) owners.
This makes all grips in resizable dialogs finally work as expected. I still consider this a #workaround to be improved.
