For some reason, you're changing behavior globally on all platforms to make
Enter select radio buttons (and the other stuff) when it was only Spacebar that
had that effect before.  I don't see any reason why that change should be made.

         return;
     // If an unselected radio is tabbed into (because the entire group has nothing
     // checked, or because of some explicit .focus() call), then allow space to check it.
     if (element().checked())
         return;
     dispatchSimulatedClickIfActive(event);
