Tabindex issue in dialog

Tabindex is not working correctly in 7.x-2.3 (didn't check dev). Jumps out of dialog and doesn't focus close button.

It's an Dialog UI issue. But it's a small fix I found here http://webzing.com/blog/?p=5 It's just a one-liner:
uiDialog.bind('keypress.ui-dialog', function(event) {
to
uiDialog.bind( "keydown.ui-dialog", function(event) {

Could this be fixed in jQuery Update? It's fixed in the latest jQuery UI but it's a looong way until it gets into Drupal.
