mac: [Yosemite] Fix bug where zoom button causes fullscreen mode. (reland)

----------------Reland Description---------------------------
Fix a type error. NSArray comparators return a NSComparisonResult.

----------------Original CL Description---------------------------
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.
