Test file that demonstrates unexpected behavior for calling focus() on div with tabindex=-1

When Voiceover is enabled:

Action: calling the javascript focus() method on a div with a tabindex=-1
Expected result: move focus to the div, so that subsequent VO+right arrow would move VO cursor to first child element. 
Observed result: moves the Voiceover cursor to the first child in the container.

Oddly enough, simply putting an aria-label on the div results in the correct behavior:
Action: calling the javascript focus() method on a div with a tabindex=-1 and an aria-label="foo"
Expected result: moves the Voiceover cursor to the first child in the container.
Observed result: expected result.

Also notable is the fact that a div with a tabindex=-1 gets an accessibleRole value of Group
(see Bug#148646: https://bugs.webkit.org/show_bug.cgi?id=148646)

See attached test file for example and steps to reproduce.
