Thanks for the report.  Arash, it turned out that our expectation[1] was
not correct.  The style file beamer.el requires to be processed with
`TeX-run-style-hooks' in order to obtain its class options for use with
completion.  Just loading it with `TeX-load-style' is not enough because
hyperref.el, which defines the variable
`LaTeX-hyperref-package-options-list', is loaded only through
`(TeX-run-style-hooks ... "hyperref" ...) in the style hook created with
`(TeX-add-style-hook "beamer" ...)'.

What way should we take?  To partially revert the change discussed in
[1]?  Or to fix the style file each time similar problem occurs?  Or
somethig else?

Regards,
Ikumi Keita
