+			// with another element, the target of the mouse/click will be the new
+			// element underneath that point.
+			//
+			// Aside from proximity, we also check to see if the target and any
+			// of its ancestors were the ones that blocked a click. This is necessary
+			// because of the strange mouse/click target calculation done in the
+			// Android 2.1 browser, where if you click on an element, and there is a
