When called from the Dynamic Context Menu (spacebar), it works just fine

Operator requires an execution override to work properly:'INVOKE_REGION_WIN')

This should probably be the default behavior for this operator call.

Seems to be an invalid pointer when this operator is directly executed from python instead of being invoked before.
