braketbar=true in output
Issue Summary
The custom attribute used in
https://github.com/mathjax/MathJax-src/blob/develop/ts/input/tex/braket/BraketMethods.ts#L85
appears in SVG and HTML output, creating invalid markup.
Steps to Reproduce:
- Visit https://www.mathjax.org/#demo
- Paste
$\set{c_{i,j}| i \in I, j \in J}$ - check DOM to find
|output havingbraketbar="true"
It looks like that should probably be a data-* attribute.
Slightest of pings on this one (now that v4 is in alpha).
I'd make a PR to make the trivial change but I couldn't work out where this attribute is actually used (I had assumed it's for SRE but don't see it there either).
It's on the list of things to do (the v4.0 milestone, and assigned to me so I will be sure to see it).
I've made the change as part of mathjax/MathJax-src#906, which was updating the braket package in other ways. While MathJax doesn't use this attribute, I suspect SRE uses it somewhere, so @zorkow may need to do something in SRE to accommodate the change.
