I don't think we can be making comparative judgements of specific implementations in the spec, I think we should just have a paragraph describing the issue. We can link to appendix B.3 of mathml-core (assuming we land the PR to update that and also, we could link to MathFonts.github.io accents test to tell people to see which characters stretch in current implementations.

This still needs work/discussion. Implementations are all over the place (or don't work for any character). Not sure what we should do.
