[website] highlighting breaks the MathML render

[xtuc]

When you do a search and have the highlighting turned on some MathML formulas don't render anymore.

Example:

• On: https://webassembly.github.io/spec/core/valid/modules.html?highlight=a#data-segments
• Off: https://webassembly.github.io/spec/core/valid/modules.html#data-segments

I'm personally using the search often and need to edit the URL by hand to understand the formulas.

Interesting. That's unfortunate, but is there anything we can do about this? The underlying problem is that MathJax, which is the math rendering package used here, is a JavaScript-based kludge (as are its alternatives) and the web still hasn't grown a proper solution (like MathML).

One thing you could do is not apply MathJax in browsers that nave native MathML support (currently, Gecko and WebKit-based browsers). Igalia is working on MathML in Chromium, so this could end up being a practical solution soon.

[rossberg]

Sounds good, but is serving different pages to different browsers even possible with GH pages?

Good to hear that Igalia is working on MathML, though!

Do you know if the highlighting is actually useful? You can use Ctrl+f instead (once you get on the page), that sounds like a good compromise to me.

@rossberg I was imagining a JS snippet would decide which to show on the client side. Not sure if this would be a ton of trouble to implement.

[rossberg]

@littledan, with MathML the math isn't generated by JavaScript but is a static part of the document. You could probably set it up differently somehow, but I don't know of tools that support that.

I don't see any difference here. I assume because we've switched from MathJax to Katex? Can we close this?

Never mind, I see the issue now.

[rossberg]

Closing as won't fix.
