>> The native color chooser is an example of a window that can become the key (focused) window but cannot become the main window.

>> A window that is main but not key does not own the keyboard focus, but it appears active, and if it is using the screen menu bar,

>> The current macOS AWT does not support this combination of window states. A Java window is either key and main, or neither.
>> When the color chooser becomes key (obtains focus), the Java frame resigns both key and main status.
>> This change allows the key window status to be resigned while retaining the main window status, with the appropriate behavior.
>> Note that with this change, it remains impossible to implement a Java window that behaves like the native color chooser (i.e., can become key but not main).
>> That would require a much bigger change.
