Summary:
To theme our UI, we call setBackgroundColor: on an NSWindow presented as a sheet, to change the color of the entire sheet's background.

Steps to Reproduce:
- Create a window using an NSWindowController subclass.
- Override windowDidLoad to call [self.window setBackgroundColor: [NSColor colorWithCalibratedWhite: 0.15 alpha: 0.95]]; and then call through to super
- Present the window as a sheet using NSApplication's beginSheet:modalForWindow:modalDelegate:didEndSelector:contextInfo:

Expected Results:
You should get a dark grey sheet, partially transparent.

Actual Results:
The sheet has a bright white background color.

Regression:
This worked fine on 10.7-10.9.x
