Mac: restoreGeometry() from a window that is zoomed then resized places the window at wrong location

If a window is saved after it's zoomed then resized without being moved, the restored window is placed at the pre-zoomed position with the new size. This is tested on the Mac.

Steps to reproduce:

1. Use the attached main.cpp in a GUI app. Build and run the app.
2. Click the green zoom/maximize window button.
3. Grab the resize corner and resize the window. DO NOT move the window.
4. Close the window.
5. Run the app again.

Note the restored window is placed at the same location as it was before the zoom/maximizing. But the size is the adjusted size.
