i think that's a bit worse because it's arbitrary. you only want to remove the thing when it's definitely not in the viewport, but also not any longer than that
well looking at the Photos app, apple doesn't really apply Reduce Motion to gesture-based animations - it doesn't seem to affect the lightbox in Photos at all actually. so I am pretty happy with just overriding it here
I don’t think reduced motion should apply to interactive animations.
You wouldn’t want drag and drop to not follow your mouse because of reduced motion, for instance, and pulling away a lightbox is the same idea.
