==================== Summary ====================

Ancestors: Morphic-mt.1249

Fixes a bug regarding shadows. When toggling the shadow via the Theme menu, update all windows in the world.

In the long term, we might want to refactor the #menuAppearance3d preference. There is much room for improvement in the shadow-related source code.
