// the pointing device (mouse, finger, stylus, etc.).
// A click event's target can be imprecise, as the value will be
// the closest common ancestor of the press (mousedown, touchstart)
// and release (mouseup, touchend) events (often <body />) if
// the the target of each event differs.
// We need the actual event targets to make the correct decisions
// about user intention. So, consider the down/start and up/end
// items below as the deconstruction of a click event.

// id value is stamped on the event. This id is inspected
// in the document's click handler, and if the id doesn't
// exist or doesn't match this detector's id, then trigger
// the outsideClick callback.
//
// Taking this approach instead of checking if the event's
// target element exists in this component's DOM sub-tree is
// necessary for handling clicks originating from children
// rendered through React's portals (EuiPortal). The id tracking
// works because React guarantees the event bubbles through the
// virtual DOM and executes EuiClickDetector's onClick handler,
// stamping the id even though the event originates outside
// this component's reified DOM tree.
