This is part of a patch to address a jQueryUI bug. The bug is responsible for the inability to scroll a page when a modal dialog is active. If the content of the dialog extends beyond the bottom of the viewport, the user is only able to scroll with a mousewheel or up/down keyboard keys.
The javascript patch overwrites the $.ui.dialog.overlay.events object to remove the mousedown, mouseup and click events from the list of events that are bound in $.ui.dialog.overlay.create.
