Right, the spec there says:

"A start tag whose tag name is "select"
- Reconstruct the active formatting elements, if any.
- Insert an HTML element for the token.
etc."

Which is what webkit does. However looking at the web inspect in Opera, it looks like it does:

"A start tag whose tag name is "select"
- If the current node is an option element, then act as if an end tag with the tag name "option" had been seen.
- Reconstruct the active formatting elements, if any.
- Insert an HTML element for the token.
etc."

And doing the same in Webkit also fixes it. It also fixes two failing tests in the html5 test. However it still has one failure in webkit01.dat. I take it those are webkit-generated tests rather than spec-generated?

Interestingly if I change the stray <option> to a <datalist> in opera it exhibits the same bug we see here with <option>. So it looks like it has implemented the workaround for <option> only.

I filed a comment on this to the html5 spec and referenced the bug here.
