Additional context
- Might be related to recent MathJax version bump
Uncaught (in promise) TypeError: this.parent(...) is nullerror flood consoleUncaught (in promise) TypeError: Cannot read properties of null (reading 'replaceChild')when using Chromium/Chrome
- Sometimes it works sometimes it doesn't after page refresh
- I've tried clearing cache multiple times
- Maybe related to cdn cache?
We have deployed a fix, now it should display properly.
Feel free to keep us posted, thank you!
Didn't test throughly but seem fixed.
Thanks!
