Comment 32 for bug 1605937

This patch disables expansion on mouseover. Is there a reason to be doing this? If there is something that expanding is useful for, I think it is sufficient to do it when an indicator is clicked. That still happens with this patch (when used in a window manager without composting, a black field will be drawn across the screen under the panel and the clicked indicator's menu).

I think this could resolve the "focus stealing" problem some users are experiencing with wingpanel.
