Ticket #4629 Dialog events not being triggered

If I get that correct, dialog uses draggable and resizable, but
doesn't let the related events bubble up to the dialog widget itself:
http://dev.jqueryui.com/ticket/4629
The events are documented for dialog (with inconsistent naming as he
mentions), but is that really the desired behaviour? The specification
doesn't mention these at all: http://wiki.jqueryui.com/Dialog
