1196097 - Use SameObject for source attribute of ServiceWorkerMessageEvent interface

Status: RESOLVED INVALID

(Core :: DOM: Service Workers, defect, P3)

Description

[Dimi Lee [:dimi]]

https://slightlyoff.github.io/ServiceWorker/spec/service_worker/index.html#serviceworkermessage-event-section
the |source| attribute of ServiceWorkerMessageEvent interface defined in spec is:
[SameObject] readonly attribute (ServiceWorker or MessagePort)? source;

But for now if we try to use |SameObject| over union type attribute, it will show "An attribute with [SameObject] must have an interface type as its type" build error.
We should use |SameObject| once IDL spec is changed.

In bug 1311324 we removed ServiceWorkerMessageEvent in respond to it being merged into HTML's MessageEvent by https://github.com/w3c/ServiceWorker/issues/989 (fix commit https://github.com/w3c/ServiceWorker/commit/8538a55d5eaa2f16fdaabffa23b9fc2bc0e302a5). HTML does not specify the source is SameObject at this time.
