Can we use CustomEvent.detail for this?
https://developer.mozilla.org/en-US/docs/Web/API/CustomEvent

new CustomEvent("clipboard-" + event.type, {detail: event});

Did not work for me.

+        event.deepActiveElement().dispatchEvent(eventCopy);
+        if (eventCopy.handled)

[lushnikov, 2016/07/12 03:21:55]

Can we check for eventCopy.defaultPrevented here?

[pfeldman, 2016/07/12 20:56:46]

It does not work on custom events.
