Changing the beginning and end regexes to the following seems to work
well (I've just added a non-capturing group for \(\) or $$ so that
begin-end blocks can be nested inside inline math environments).

(setq org-element--latex-begin-environment "^[ 
\t]*\\(?:\\\\(\\|\\$\\)?\\\\begin{\\([A-Za-z0-9*]+\\)}")
(setq org-element--latex-end-environment "\\\\end{%s}[ 
\t]*\\(?:\\\\)\\|\\$\\)?$")

I'm going to test this a bit before submitting it as a patch to make
sure it doesn't cause any issues. If you have any tricky fragments you
want to test it on please let me how it works!
