Popup: blue focus flash on android 4.2

So I tested this with Browserstack on android 4.2 and it fixed the problem.  However, when I run "grunt test" there are a number of test cases failing.  @arschmitz suggested I do a pull request so he can take a look.  So don't merge if it's breaking tests! :)
Since we're modifying the test extensively, let's get rid of the Hungarian notation here. Let's just use ```link``` and ```popup```.

We should also follow the style guide and have one initialized variable declaration per line.
