why do we need this one? Does it not change the behavior for the other
activities?

Oh. This flag is to tell the CAB bar to overlay on chrome's content, instead of
squeezing the entire UI downwards. (Similar to use framelayout instead of
vertical linearlayout.)

In chromeTabbedActivity and DocumentActivity we already sets this flag
programatically. Yet it seems having an xml configuration is too wide and it
harms web apps. I moved this flag to the activity.
