Hmm, good point.
It looks to me like the relevant function is
org-element-latex-fragment-parser, and the code for that hasn't changed
much in several years (last change was 2017). (Also, I was wrong,
parsing latex fragments is not done with just a regexp.) I can confirm
that this function parses "$foo" in "$foo$ bar" as a latex fragment, but
not in "$foo$-bar"
Not sure if the problem here is the code or the documentation. Perhaps
the documentation should be updated to reflect the current behavior?
