That's defined by defun generated by elisp macro `TeX-auto-add-type'.
See
...
(TeX-auto-add-type "environment" "LaTeX")
...
in latex.el and the definition of `TeX-auto-add-type' in tex.el. ;-)
With respect to the format of the entry, see info node `(auctex) Adding
Environments'.

The reason why your customization was ignored is that "the longest entry
wins" rule described in the above info node. Previously, the entry for
the frame env was of the form
("frame" (lambda (...) ...))
, which was 2 elements long. In that case, your local customization was
used. However, now the entry in beamer.el is of the form
("frame" LaTeX-env-args [TeX-arg-beamer-overlay-spec] ...)
, which is 6 elements long.
After you copied the entry and tweaked it, your local entry becomes 6
elements long, too, so it becomes effective again.

That's default behavior of `TeX-insert-macro' (C-c C-m), when the
customize option `TeX-insert-macro-default-style' is
`show-optional-args'. You can customize the behavior by setting that
option to `show-all-optional-args'[1]. Note that
`show-all-optional-args' affects every C-c C-m as well.

Hmm, that would require customized elisp function for frame environment.
Patches welcome. :-)

Thanks, I'll see what I can do when I have enough spare time.
