Seems to pass my tests.  Not sure if you missed the alternate fix I
proposed in https://debbugs.gnu.org/33887#94 or not.  It does have the
disadvantage of leaving (car (syntax-ppss)) unreliable for any other
code which uses it.

Here's a patch against master that should cover the remaining cases
Vincent raised:

And about the highlighting of quoted text outside tags, we can just
disable fontification, while leaving the syntax code untouched:
