That's odd.  Font locking should happen before folding, but it does
not.  At least it seems so.  The section macros have a `fontified'
text property with the value nil.  I'm not sure why this happens
because font locking is already forced in `TeX-fold-buffer' by calling
`jit-lock-fontify-now'.  This call was actually introduced to take
care of non-visible portions of the buffer.  It does get a bit better
if `font-lock-fontify-now' is used instead (and the `when' clause in
`TeX-fold-buffer' removed).  Then at least the folded section macros
will be fontified correctly.  The labels are still wrong, though.
I'll have to investigate further why this is happening.  If
`jit-lock-fontify-now' just let me debug it. )c:

As long as they are small this would even be the preferred way for
providing screenshots.
