2. make an use that map <img usemap="#the-map">
3. throttle your bandwidth

Live test case: http://medialize.github.io/ally.js/tests/browser-bugs/gecko-area-loaded.html


Actual results:

before the `load` event on the <img> the <area> elements of the associated <map> are neither focusable nor tabbable.

Also reproducible in Firefox Nightly 37.0a1 (2014-12-20).


Expected results:

I can focus and tab to <area> elements of <map>s of <img>s that haven't fully loaded yet. Every browser but Firefox allows this.
