I have noticed some of my older blogs and comments have some of their $$$\TeX$$$ mathematical expressions incorrectly rendered in their own line instead of in the line of text, which can be really distracting to read.
Examples: https://codeforces.me/blog/entry/72593 ($$$\mathbb Z /p \mathbb Z$$$, and the large numbers in the spoilers)
https://codeforces.me/blog/entry/73211#comment-575285 This comment had it especially bad
I'm not sure what the cause of this is, and there is no discernible pattern as to which expressions and comments are affected.
