Removes a component’s refresh handler method from the refresh process.

refreshID—(Required) A numeric refreshNode.handle value that uniquely identifies the node of this component on the refresh tree. You obtain the refreshNode.handle value when you call registerRefreshHandler().


Use the unregisterRefreshHandler() method to remove a refresh handler's registration from the refresh tree. Child contexts are temporarily retained to ensure that they are refreshed, in case unregistration takes place mid-refresh.

You must unregister your component’s handler callback methods in disconnectedCallback().
