Customizer: "Select a file" link cannot be opened from keyboard

[SergeyBiryukov]

"Select a file" link in Background Image section doesn't work when trying to open it from keyboard (pressing Enter does nothing). Tested in Firefox 17 and Chrome 23.

First reported in #21283, see ticket:21283:55 (item 4). See also ticket:21283:67 (item 1).

Confirmed in FF & Chrome on both Mac & Linux

According to koopersmith, this is not an easy fix: "Plupload's shimming it, so we have to pass the event through. I thought it was only broken in html5less browsers, though..."

i created a patch that fires a click event when the user hits enter on the link (attached) - a bit of a kludge perhaps, but does make the page accessible, tested in both firefox and chrome on my mac.

Seems good to me.

Refreshed with proper path and tabs instead of spaces (per ​WordPress Coding Standards).

In 23399:

Allow Backround Image's "select a file" link to be activated by pressing return on the keyboard.
