Not sure what you mean by “real HTML parser”.

One thing to watch out for is improper HTML when users type a literal
‘<’. I had a lot of users lose part of their comments because
everything after a standalone ‘<’ was incorrectly filtered.

This was with WordPress + PHPMarkdown (blog comments). What made it
worse was that it was the filtered content which went into the
database, so once filtered, the content was gone.
