Detach every active listener for one event type from a DomItem's element, regardless of which EventListener
descriptor each one belongs to, and clear that event's activeListeners bucket. Unlike deactivateListener,
this does not update the listenerActive/activeResponder state on the individual descriptors.
Parameters
eventName: string
The name of the trigger event whose active listeners will be revoked.
Detach every active listener for one event type from a DomItem's element, regardless of which EventListener descriptor each one belongs to, and clear that event's activeListeners bucket.
