The toolbar's buttons are updated on screen rotation. In particular
their alpha value is set to 1 even if the omnibox is focused. It
displays the back/forward button as they are hidden during the animation
of the omnibox focus.
This CL fixes it by not updating the alpha value if the omnibox is
focused.
