#12518 closed bug (fixed)

Don't use offsetWidth in jQuery.event.trigger()

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.
