/**
 * An event target to handle communication between instances of Dialog and Popover.

 * which are opened while an Dialog is rendered. While such Popover instances remain open, the Dialog
 * will not close on Esc.
 *
 * This operates on the assumption that any Popover instance that is opened after an Dialog is
 * rendered on the screen is part of the content of said Dialog and should be closed before the Dialog
 * itself.
