It's true that this custom element's contentEditable would have completely different semantics from that on other elements but that wouldn't break websites that use this custom element as long as authors are only accessing contentEditable property on instances of the custom element for semantics C.

I forgot the exact details, but we had some amount of trouble when we
introduced min and max attributes due to sites using expandos with the
same names.

I think we need something better than encouraging certain conventions
if we want this to work.
