+      An event that the modal instance emits when it is about to close. It emits a <stache-code>SkyModalBeforeCloseHandler</stache-code> object with a <stache-code>closeModal</stache-code> method that closes the modal. If a subscription exists for this event, the modal does not close until the subscriber calls the <stache-code>closeModal</stache-code> method.
