Latex math in feedback is broken

[rakfisk1]

When trying to give feedback using either $math$ $\math$ or $mathblock$ $\mathblock$ the entire contents of the block become invisible in preview and feedback.

It looks like the HTML sanitizer introduced in v6.2 with #1275 also escapes $math$/$mathblock$ for Devilry's latex_math modules.

It seems to affect a few of the Markdown tags we want to allow:

• $math$/$mathblock$ are escaped :x:
• markdown code blocks (```) are displayed on one line without indentation :x:
• <code> blocks are displayed as multi-lined, but without indentation :x:

My guess is that HTML-sanitizer's keep_typographic_whitespace=True enables multi-line code blocks, but lack support for code indentation or is missing a setting.

Update Jan 30: we are looking at addressing this with a patch (6.2.3)! :wrench:

Solved in v6.2.4.
