1117544 - multiple FocusEvents for focus change within the same ShadowRoot

Status: RESOLVED INCOMPLETE

(Core :: DOM: Core & HTML, defect, P5)

Description

[Rodney Rehm]

Attachment: gecko-shadow-dom-multiple-events.html

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.8; rv:34.0) Gecko/20100101 Firefox/34.0
Build ID: 20141125180439

Steps to reproduce:

1. create a ShadowDOM structure (see attached test case)
2. bind focus event listener to document
3. focus element within the ShadowRoot
4. focus another element within the ShadowRoot

Live test case: http://medialize.github.io/ally.js/tests/browser-bugs/gecko-shadow-dom-multiple-events.html


Actual results:

I received two focus events, both naming the first ShadowHost as the event.target.

Also reproducible in Firefox Nightly 37.0a1 (2015-01-04).


Expected results:

There should have been only a single focus event dispatched, because from the document's perspective nothing changed, the focus is still on / in the ShadowRoot. The second event, should've had event.target === event.relatedTarget and should have thus not have been dispatched according to http://w3c.github.io/webcomponents/spec/shadow/#retargeting-focus-events
