            Bug ID: 23186
           Summary: EventListener argument of addEventListener and
                    removeEventListener should not be nullable
           Product: WebAppsWG
           Version: unspecified
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DOM3 Events

The definition table of arguments of addEventListener and removeEventListenr
defines the EventListener as nullable ("✔").

However, the explanation documents: The listener parameter MUST be an object
that implements the EventListener interface or a function.

Additionally, I have no idea the purpose of the argument nullable.

So, I think that they should be "✘".
