Does this mean that when we create a single window without activation, it's not
active? 

[flackr, 2014/02/14 20:00:02]

Correct. This may be to prevent stealing input focus in case you are midway
through typing a password or something, but I can verify.

We probably should investigate what's the ideal behavior for this case. (outside
of the scope of this CL)
