 // floating dropdown bar, and managing the tracking area associated with the
 // dropdown.  This class does not directly manage any views -- the
 // BrowserWindowController is responsible for positioning and z-ordering views.
 //
 // Tracking areas are disabled while animations are running.  If
 // |overlayFrameChanged:| is called while an animation is running, the
 // controller saves the new frame and installs the appropriate tracking area
 // when the animation finishes.  This is largely done for ease of
@@ skipping 88 matching lines @@
 // effects, such as modifying the system fullscreen mode (menu bar shown state).
