Sigh.  If you use preview-latex on material where _some_ of it is made
invisible using TeX-fold-mode, the desired outcome will be to get the
display, and get it once only.

I can't vouch for the patch being either a step in the right or wrong
direction.

But I'd clearly like to see fewer "I think it should work and can't
imagine anybody actually using it, anyway" patches at this point in
the game.

If we don't have the time or resources of assessing the ramifications
of a patch, there is really little incentive to not rather try them
out in the course of version 22.2.
