Got it!

Indeed!
Now $$ is highlighted as I wanted, and the syntax preserved inside.
No "containedin=..." needed.
However (why there is always a however?), the other problem persists.
I want to highlight, say, the beginning and end of proofs, and my old
highlighting does nothing:
hi proof cterm=bold ctermfg=black ctermbg=cyan guifg=black guibg=cyan
syn match proof /\(\\\(begin{\|end{\)\?proof[}]\?\)\|\(\\qed\)/
Adding "containedin=<WHATEVER>" highlights the patterns, BUT then that
also highlights most "}" as errors (this sounds like a bug in the
highlighting syntax to me...)
If the file after/syntax/tex.vim only contains this two lines
hi proof cterm=bold ctermfg=black ctermbg=cyan guifg=black guibg=cyan
syn match proof /\\qed/ containedin=ALL
then most "}" are highlighted as errors. I can grab the screen and
post it on my webpage if needed. The "containedin=ALL" seems to
have some problem.
Thanks a lot!!
