Test case for window.getSelection with onfocus, onclick handlers

When an onfocus handler is registered on a div containing another div with text, window.getSelection().focusNode reports null in said onfocus handler. If the handler is an onclick handler, it correctly reports the focusNode as a HTML div element.

This is due to the fact WebKit sets selection after setting the focus.

Ojan, Alexey:

Do you think we should change the WebKit's behavior so that we set the selection first and then focus?  This will make our behavior consistent with IE.

Have you tested Firefox?

I'm not aware of any reason why such a change would be bad per se. But I don't think that we allow unfocused (inactive? I'm confused about the difference) elements/frames to be selected, because having multiple selections in a window is bad UI.

FocusController / SelectionController is in the realm of the HTML Editing component.

I am not sure on web-spec but just wanted to share latest results across all browsers using attached test case. Thanks!
