this will always be a no-op with the condition above

Removed.

I think this check can just go at the start of ShowWindowNearDock() (i.e. return
early if visible), and it will fix http://crbug.com/289872 as well. Not sure if
it should re-show if it is in the 200ms window when it is fading out... I'd say
initially "no"

Done.
