Unless somebody objects, I'll go with (a) then.

I still think that consuming auto hiding events is a better default. But 
probably not that better to cause some incompatibility problems. Eric, 
would you mind if we don't change the default?

At least in Safari, it seems that it does not consume mouse events by default that cause the popup to be closed. However I know Cocoa has an API for specifying what this behavior should be. If we add such an API, we probably will want to make sure it defaults to some platform specific value rather than always defaulting to "true" or "false"?

If you invoke preferences and in one tab page expand a combo box, then click on an another control in the same tab page, the function of that other control is not executed. Only if the interaction involves multiple windows, I can see that the event is not consumed. With the property we will control this behavior among controls / popups of a single window, while leaving the behavior between multiple windows OS dependent.
