You could put this, the thing that starts it, and initialize in a shared helper
script.

I have two other CLs testing .focus() and .openWindow(). I will refactor that in
the next one.

(Reason is that this CL is also fixing a bug and I prefer to have the feature
bug-free as soon as possible and doing the refactoring would be better with
another feedback cycle.)
