Fix slow anim when using a gesture to open status bar pulldown

When using a custom launcher, like Nova, it is possible to set a
gesture to open the status bar pulldown. It does not open at the
same speed as when using a finder to pull down from the top
of the screen at the status bar. This fixes that.
