Status: ASSIGNED

(Core :: DOM: HTML Parser, defect)

Description

[Simon Pieters [:zcorpan]]

https://parsetree.validator.nu/?parser=html5&content=<%21DOCTYPE+html><option>&submit=Print+Tree

https://parsetree.validator.nu/?parser=html5&content=<%21DOCTYPE+html><optgroup>&submit=Print+Tree

Should have no errors.

[[
If there is a node in the stack of open elements that is not either a dd element, a dt element, an li element, an optgroup element, an option element, a p element, an rb element, an rp element, an rt element, an rtc element, a tbody element, a td element, a tfoot element, a th element, a thead element, a tr element, the body element, or the html element, then this is a parse error.

Similar for <option></html> (it seems <option></body> does not get a parse error with the V.nu HTML parser).

I was thinking in terms of months so that's great :)

This is not actually observable in Firefox, but this should still land on m-c to keep the sources in sync. Test cases should go into html5lib.
