I am working on tuning the mfrac@bevelled polyfill and ran into a big difference between Firefox and Chrome. Firefox (which I think is correct): <img width="864" height="584" alt="Image" src="https://github.com/user-attachments/assets/131944a0-5a10-40db-80e6-6edd484eb104" /> Chrome: notice the bounding box has lots of extra room on the left and right. <img width="1699" height="299" alt="Image" src="https://github.com/user-attachments/assets/acac9626-3a07-4a56-bb26-f38ad457bfae" />

This is likely Chromium bug https://mathml.igalia.com/project/#-width-of-stretchy-operators-blocked-on-chromiums-refactoring
Not sure why this is reported as a spec bug and not an implementation bug.
