Right, I think this makes more sense than the current code (although I don't exactly remember what is the reference point for strechy operator painting). At least, this will be compatible with the current code when lspace=rspace=0 which is the case for accents (see e.g. https://bug-72828-attachments.webkit.org/attachment.cgi?id=229368).

BTW, we have various tests in LayoutTests/mathml/ ; I think you should check whether they won't be broken by your changes (or will need a small rebaseline) and add a new one for the present use case.
