Bug in jQuery 1.4a1 focus()

Bug in jQuery 1.4a1 focus()

Hello,
I have found a bug in the focus() function in jQuery 1.4. The focus()
function simply does nothing in jQuery 1.4a1 when trying to trigger
the event. For example:
$("input").focus();
This does nothing. In jQuery 1.3.2, this would focus the input
field. Here is a test page: http://dl.dropbox.com/u/534786/focustest.html.
Click the button to call focus with jQuery 1.4a1.
Hope this helps!
Devon
