Expand account widget based on screen size

Is your feature request related to a problem? Please describe.

With the wider display(s) it would make sense to expand the user account dropdown to reveal more of the email. Feedback was that it's quite strange to have all this free space but still cram the email in a tiny spot.

Something like expanding the size of the button to another longer width and still ellipsing overflow should be good enough.
