Hi blink-dev@, As implemented in Chrome today, attempting to create a BroadcastChannel instance in an opaque origin context will result in an exception being thrown. We plan to ship a minor change that will allow BroadcastChannel instances to be created and used in these contexts, which will align Chrome with the HTML standard [1] and with Firefox / Safari. We don’t expect any breakage as a result of this change, and there is existing web platform test coverage [2] [3] to ensure that BroadcastChannel works as expected in opaque origin contexts. A CL implementing the change [4] has been reviewed and is ready to land, so we expect this to ship with M102. This effort is tracked by crbug 670024 [5].
Let me know if you have any questions.
