I'd listen to focus event independently to decouple new nice code from this old
ugly code.

Listening for focus is a bit complicated because of ShadowRoots, but I moved it
to WebInspector._focusChanged instead of setCurrentFocusElement.

     } else if (WebInspector._previousFocusElement)
         WebInspector._previousFocusElement.blur();
 }
