Unnecessary focus ring is seen on guest profile icon.

Adding release block label, please undo if not the case.

Able to reproduce the issue on Mac OS 10.11.6 using chrome latest canary M54-54.0.2823.0 as well.
	
Rogerta@ - Any update on this bug? Since this issue is marked as RB-Stable could you please have a look in to it. Incase if it's not related to your change please feel free to reassign it to the concerned Dev person.

Thanks!

Sorry about the delayed update, this issue is indeed cause by the suspected CL. I will submit a fix in the next few days. Thanks!

This isn't releaseblock-stable, since this is behind a flag.

I tried with 54.0.2823.0 and 54.0.2828.0 on my MBA, and I am not able to repro.  I have seen similar problems with focus rings before on macs, and I suspect there is a user setting that causes this.  Might be worth playing with OS user settings.

Also, if you press the TAB key the ring appears, allows you to tab through the menu items.  This is by design wrt mac UI.  Are you sure you didn't press a key or something (in the video, there is a delay for the focus ring to appear)?

I was able to repro on my mac, and the problem was that these user menu buttons we had don't disable focus ring when the button itself is disabled. I will submit a fix that disables focus for any disabled buttons in the user menu.

The above CL would prevent focus rings from appearing on disabled buttons.

Just to update:

Issue is fixed in latest canary build 54.0.2831.0

Rechecked this on chrome version 54.0.2835.0 on MAC 10.11.6. Fix is working as intended. Adding TE-Verified labels.
