mathstodon.xyz users: I've found out why LaTeX sometimes isn't rendered: it's a bug in MathJax! See github.com/mathjax/MathJax-src for the details.
For now, I think you can avoid it by not putting a math delimiter at the start of a line. Even a single space should be enough to avoid the bug.

@christianp Oh, cool! Thanks for looking into this!

@christianp Not sure how that creates this problem ...

@christianp Oh, bizarre, it did exist, and now it doesn't.

Very odd.

OK, seems to be fixed. Thanks.
