It is visible in Firefox
but there are problems with the strike being too small and not being distinct enough from the y. Vanilla MathJax is like the SVG and LaTeX is like
We generate the following MathML
<menclose notation="updiagonalstrike"><mi>y</mi></menclose>
Unfortunately, displaying this is not possible with the current MathML Core spec. https://github.com/w3c/mathml/issues/216
@NSoiffer suggested using this polyfill: https://w3c.github.io/mathml-polyfills/menclose/menclose.js. However, if we rely on JS, it is probably easier to switch to MathJax rendering in Chrome when cancel occurs.
There seems to be a way to fix this. https://github.com/w3c/mathml-core/issues/245#issuecomment-2410676518
It's a bit complicated as one has to remove menclose completely.
