Thanks for checking.  I've pushed this change to AUCTeX repo.

I think this behavior is intentional.  I think the idea is to reduce the
number of candidates in math mode in order to make the completion
faster.  But then, AUCTeX has its own way of completion (C-c RET for
macros).  This is probably the reason why `TeX-complete-symbol' is not
in focus for AUCTeX.  Check also the manual for completion[1].

Again, thanks for bringing up this issue.  I'm closing this report.

Best, Arash
