1589021 - Implement Shadow DOM focus changes

Status: RESOLVED DUPLICATE of bug 1413836

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

Description

[rakina]

Recently the focus specs got a lot of update, some of them touches on Shadow DOM.

This includes the "delegates focus" concept, where the delegation steps is defined here: https://html.spec.whatwg.org/#focus-processing-model, and also specifications on how sequential focus navigation/tabbing works with Shadow DOM (through devinition of focus navigation scopes): https://html.spec.whatwg.org/#tabindex-ordered-focus-navigation-scope

Forgot to add some things:

Here's a list of WPTs: https://wpt.fyi/results/?label=master&label=experimental&aligned&q=shadow-dom%2Ffocus

:focus also changed a bit: https://html.spec.whatwg.org/#selector-focus (Should I file another bug for that?)

FYI there's one new addition for the spec, too: https://github.com/whatwg/html/pull/5039

Ah, bug 1728864 is filed for tracking a recent spec change which is not yet landed. I think it doesn't need to block this bug.

Hi Sean, I think most of the thing is implemented in bug 1413836, could we mark this as a duplicate of bug 1413836? Or do we still need something else to close this one? Thanks!

I just checked both specs again and I think we can mark this one as a duplicate of that.
