Status: RESOLVED INVALID

(Core :: DOM: Core & HTML, defect)

Description

[jshcrowthe]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/48.0.2564.116 Safari/537.36

Steps to reproduce:

- Implement a stylesheet that uses the component-name:unresolved pseudo selector for custom elements
- Register a custom element by the same name
- Can also be seen by viewing the following URL in Firefox: http://w3c-test.org/custom-elements/registering-custom-elements/unresolved-element-pseudoclass/unresolved-element-pseudoclass-matching-query-selector.html


Actual results:

The :unresolved pseudo selector targets the resolved web component


Expected results:

The :unresolved pseudo selector should cease to target a resolved web component.

I don't know if our implementation is ready for this yet but I could be mistaken or misunderstanding. William?

Any word on this?

Comment 3

[Andrew Overholt [:overholt]]

Apparently :unresolved has been removed in favour of :defined (a bit different, I guess): https://w3c.github.io/webcomponents/spec/custom/#unresolved-element-pseudoclass .

Edgar is working on Custom Elements so is probably interested in having this tracked (I'll let him put it into the right dependency tree).

Set the dependency to the meta bug for the new implementation. And we will make sure :defined selector work well with new stuff.

Comment 5

[Edgar Chen [:edgar]]

And we are going to remove :unresolved in bug 1417829.

Comment 6

[Edgar Chen [:edgar]]

Close as INVALID given that :unresolved has been removed in bug 1417829.
Please see bug 1331334 to get more detailed status for :defined.
Thank you.
