Other information

This is a follow up to #626 which introduced object-overflow to support the same functionality. Based on feedback in the CSSWG the proposal has been updated to use the existing overflow property. This property is already respected for svg elements and the proposal aims to have consistent behaviour for all replaced elements.

This seems reasonable; I think we could call this "worth prototyping", for the same reasons discussed in #626.

(This is the same feature that was discussed there in #626, though it's been morphed to have slightly different ergonomics to avoid creating near-duplicate feature sets that apply to different elements.)

I filed https://bugzilla.mozilla.org/show_bug.cgi?id=1779332 on implementing this feature (CSS Overflow for replaced elements).

Thanks @dholbert. As this is small, let us just resolve the issue with those comments.
