After enabling native animations, Outlook is running into cases where a "finished animation" callback is called more than once. Looking at the code it's pretty clear this is because when stopping an animation, we call it with completed=false, and then try to mark the animation as completed but that function call tries to call the callback again with completed=true this time.
Fixes #2981
