nit: same comment about this holds. why aren't we putting a useful alt text
(like the avatar name or something)

Because this appears right next to the string which contains the profile name.
There's no point in having "Mike" "Mike" read out twice - might as well just
skip the first one.

If you mean the name of the Avatar (sparky, sunshine, Agent X), I don't think
that will be very useful for someone who's using a read-aloud service.

Ok. Especially since dbeam@ already LGTM'ed this

       containerEl.appendChild(iconEl);
 
       var nameEl = this.ownerDocument.createElement('div');
