Oops, had a comment, but forgot to get it to you before you landed this.

I’m not sure that a function for this is a good idea. This expression seems not much longer than the function call. I suggest just doing this work inline. It’s good to be able to see the code assuming the context is a document, I think, rather than encapsulating that in a helper.

Ditto.

OK, let's make MediaStream take a Document& instead of a ScriptExecutionContext& since code is expecting that elsewhere anyway.

It seems we should move logger to ScriptExecutionContext since we might want to do release logging in workers, especially service workers.
