// 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.
// The problem we want to solve here is have the SELECT element respond to the controller input correctly(select element one by one).
// 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
// revisited. But then, we'll need to solve a plethora of issues. So we do minimum work here to not break other things.
