Blue border outline remains on control when control goes out of focus

[ydench]

This can be replicated on Firefox and IE. Chrome does not have this issue.
Open basic example page:
http://angular-ui.github.io/ui-select/demo-basic.html
Using Tab and arrow keys navigate to the first dropdown. Pick a value, from open list. Instead of clicking Enter key, click on Tab key to move to the next control. Notice that blue border that supposed to focus current control remains on the first dropdown. Same way all the dropdowns can be outlined.
When multiple controls outlined, it is not clear which control has a focus.

Hi,

checked this but i cannot quickly reproduce this issue. What browser are you using?
Thanks.

Try on Firefox. Don't use mouse and Enter key. Just arrows and Tab keys

Interesting, I wonder if this is directly related to my issue #1934 as a focus issue could certainly be an explanation.

I confirmed this issue happens on Interent Explorer on Windows 10 64-bit.
