Original issue's description:
> mac: [Yosemite] Fix bug where zoom button causes fullscreen mode.
> 
> In Yosemite, holding down alt while clicking the fullscreen button is supposed
> to zoom the window. This doesn't work because Chrome violates unstated AppKit
> assumptions.
> 
> The problem seems to lie in hit testing the location of the zoom button.
> Reordering the subviews by moving the tab strip and the content view behind the
> zoom button fixes the problem.
