Updates layout when overflow button and alt-tab are both triggered.

Before this cl, the KQS view is closed and reopened when the
overflow button and alt-tab key are triggered one after the other.
This cl changes the behavior so that instead of reopening, the
list of task is updated and the KQS container layout is toggled
between "wrap content" and "match parent".
