Only with e10s enabled.

Hi Loic, 

Thank you for testing this, please tell me on what OS you have tested. I have tested with e10s enabled and disabled and I both cases the results are the same.

I have some updates regarding this issue. 

It is an e10s issue only on windows OS. Tested again on Windows 7 and 10, and the problem is e10s specific.
On Mac and Ubuntu it's not e10s specific.

Does it work with FF44 like Windows on OSX/Linux?

This may be reproducible in non-e10s.

I have tested on Windows versions and I think this is a e10s specific bug. When e10s is enabled I can reproduce the issue, when e10s is disabled the issue can't be reproduce it. Jimm, on what OS did you test?  I can try to run once again the test.

A couple e10s team members checked osx and linux, and I just checked Windows 7. All reproduce in a non-e10s window.

Drive-by comment: a "non-e10s window" opened while e10s is enabled by default may behave differently from a window opened while e10s is disabled by default. Depending on which you tested you may get different results. I hope it's not relevant here, but APZ in particular will remain enabled in "non-e10s windows" opened while e10s is enabled by default.

I have tested on Windows 10 Pro x64 and Windows 7 Professional x64 and I still can reproduce this issue with e10s enabled, but with e10s disabled I can't reproduce the border. Tested on Nightly 48.0a1(2016-03-09)

none e10s str:

1) click in content
2) type tab until you see a focus rect on the Opus link
3) type tab two more times to bring the focus rect to the audio controls
4) click the audio control play button

You can click the play button first too and then tab to it.

It looks like there are some differences between e10s and non-e10s with focus rect display though. Maybe we can do some testing around that?

	Jim Mathies [:jimm]
	Comment 12 • 8 years ago

Or maybe the focus rect outline was the original bug that was reported here? We triaged this but I'm beginning to think we didn't understand the original report.

Is the bug reported that the dotted line is visible through the play arrow? or is it that the dotted line is visible?

This are the steps that I performed:

1. Go to  http://people.xiph.org/~giles/2012/opus/
2. Play on one audio sample (you have 2 audio sample).
3. When you press play button you will see a dotted line when e10s is enabled.

I also added a screen recording with the bug, the recording is on Mac. I made it just to see what I am talking about. On Windows with e10s disabled that dotted border is not displayed.

	Jim Mathies [:jimm]
	Comment 14 • 8 years ago

Ok so the bug here is that in non-e10s, we don't display the focus rect, in e10s we do.

Neil, anything you can add here? I'm not sure what controls focus rects but we definitely see some differences between e10s and non-e10s.

Quite likely to be fixed by 1214293.

I think you meant bug 1174798 which should be coming up in e10s triage this week.

I tried this on Fx47.0a2 (BuildId: 20160311004048) and win8 with e10s on and I see the dotted border for the rect on which I click play. So basically I cannot repro this bug.

Can someone confirm that this was fixed by 1214293?

Tested on Mac OS 10.10, Ubuntu 14.04, Windows 7 with Firefox Nightly 48.0a1 (2016-03-24) and I can't reproduce it with e10s enabled or disabled. 
 On the same OSs tested with DevelopersEdition 47.0a2 (2016-03-24) and I still can reproduce it with e10s enabled or disabled.

Note: With Nightly is not reproducible.

I investigated this bug and managed to reproduce it in latest Nightly build id: 20160531030258.

I found a regression range :

Based on several comments that this is e10s specific only, this would not be a release blocker for Fx47 as e10s is off by default.

	Comment 26 • 8 years ago

I tested again on several OS's with Nightly 50.0a1 (2016-06-10) and here are the results:

Mac OS X 10.10 I can't reproduce this issue with e10s enabled or disabled.

Ubuntu 15.04 I can reproduce this issue with e10s enabled or disabled.

Windows 7 I can reproduce it with e10s enabled and I can't reproduce it with e10s disabled.

You'll need a build with 1174798 fixed to properly verify this.
