Thanks Stefan,

That's the only explanation that makes sense - will work around it.

We are using LaTeX to Html transformations through QtScript,  and have
found TeXworks, with user configuration tweaking, to actually be a
surprisingly  good html editor!

The problem suggests that Qt is not fully parsing things to establish
valid tags.
Qt only provides a limited subset of HTML, so it is possible for it to
be done properly.

They may have gone for a kind of short cut approach. I.e open tag
symbol present there for treat as tag with no further validation
against the subset and well formedness of html they make available.
