Event::ComposedPath doesn't handle this.currentTarget == null

[simonwuelker]

What is the issue with the DOM Standard?

Steps 4 and 5 of Event::composedPath say to

4. Let currentTarget be this’s currentTarget attribute value.
5. Append currentTarget to composedPath.

composedPath is a sequence<EventTarget>, but currentTarget is a EventTarget?, per the Event idl interface

It is unclear to me what should happen when currentTarget is null.

Is there a case where event's path is non-empty and currentTarget is null?

[simonwuelker]

After reading the spec some more I don't think this can actually happen.

[annevk]

Would adding an assert help?

[simonwuelker]

Yeah, that seems reasonable.
