Description
It's currently used to determine whether it's safe to call .focus() on an element without an error in oldIE. However, it causes a reflow and can be a performance killer. Since a direct display:none check won't catch parent-hidden elements I think we'll need to go back to a try/catch for now, but it can be removed in 2.0.
