Agreed that it was previously unclear as well.
I'm actually not sure what would be the best way to address this. It's not an easy question to answer. Have you checked how Safari / CoreAnimation deals with the transformed case?
My inclination would be "clip to the axis-aligned bounding box", because that should be the easiest to implement. But you're right that this would result in unfortunate interactions in the case where a transformed element has both an outer box-shadow and a backdrop blur.
