Is this not testable?

Yes. I was hoping there was already a test and it would fail (hence the no r?) but it looks like I’ll have to write one.

By which of course I mean, “yes, it is testable” (double negative caught me). 

Last WIP adds the test. I’m surprised that not having a result didn’t cause the EWS to fail.

Ahhhh. I meant negative not double negative!

Please feel encouraged to file a bug! I think that's a pretty bad issue.

I would write:

    ASSERT(is<Document>(scriptExecutionContext()));

But I see the file already has three places that do it the other way, calling isDocument().

> Source/WebCore/xml/XMLHttpRequest.cpp:257
> +    if (!scriptExecutionContext()->isDocument() && type == ResponseType::Document)
> +        return { };

As I said above, I like the is<Document> style better. If you wrote it is<Document>(scriptExecutionContext() then you would include an unnecessary null check.

But it’s annoying that the assumption that script execution context is non-null is implicit; when called from script I guess that is sort of obvious, but on the other hand it’s annoying that it’s called “script execution context” yet we stash it when created and don’t get a fresh one when being called from script again.

I kind of wish there was a version that returned a reference and asserted.
