Please double-check whether you need to use `Region.clipScale()` instead.

I actually do not remember when to use one over the other. Maybe if you find a review request for the patch where these methods were added, you can confirm which one should be used. I checked the current source, and it seems that we randomly use one or the other, which seems incorrect.
