Seems it's only triggered when electric-indent-mode is on.
And the error is in sgml--syntax-propertize-ppss, a function that was
added after mhtml-mode was written.
A quick attempt at fixing it (adding "sgml--syntax-" to
mhtml--crucial-variable-prefix) didn't help, so I'm just going to Cc the
people who might have better idea.
