MathJax issue ?

[damien-git]

aXe seems to have a hard time analyzing https://users.math.msu.edu/users/wongwwy/expository/torsion.html . I noticed the issue first with axe-webdriverjs. I also tried the aXe plugin in both Firefox and Chromium, and had to force stop it in both cases.
Possibly because of the use of MathJax ?

Looking at the page, it seems the color-contrast rule is taking 23 seconds to complete. Axe-core's color-contrast rule is one of the slowest rules we have, and it looks like all the individual math symbols are being checked for color contrast.

Interesting. Would there be any way to accelerate the process for similar pages ?

[straker]

Right now our only workaround is to turn off the color-contrast rule for such pages.

axe.run({
  "rules": {
    "color-contrast": { enabled: false },
  }
});

It is also worth noting that we're working on a major performance improvement to the color-contrast rule. That will hopefully help to solve this.

This is good news.
I wrote a domain accessibility audit web app based on axe that can check many websites at once and report statistics. Improved axe-core performance would be a must for that.

ID'd as color-contrast issue. We're going to make one entry into the release notes for all color-contrast fixes/enhancements.
