	// For example, in all the browsers, if you scroll the mouse wheel on the frame, the SELECT element disappears and the actual frame scrolls.

	// For any modal input needs on a web page, the users are advised to use the Z-layer technique with Javascript/CSS - http://jqueryui.com/demos/dialog/#modal-confirmation.

	// But the button event information is lost by the time we are in the EA::WebKit::View. For the foreseeable future, there is no candidate
	// other than html SELECT element which is implemented as a modal popup inside EAWebKit. So inside EA::WebKit::View, we create a dummy
	// button event from the Jump direction and make SELECT respond to it. If any other object starts using the modal input, this would need to be
