Would it help to empty the grab-bag when the user modifies the rotation
(or modifies the object in any way)?

The idea with grab-bag was to use that during export, and the UI to
empty them grab-bag when the user modifies the object. In practice, I
think only impress shapes drop the smartart grab-gag on text edit,
nothing else implements such emptying.
