b/17299906 Cancel button is now disabled when the delete button is clicked. This will prevent users from canceling the delete before the delete is complete.
Added some UX improvements for delete modal -- confirm/cancel buttons are never re-enabled after delete success, and modal backdrops are now not clickable during pending delete operation
Added 'disabled' class handler for modal backdrops
