I think you may need to retain the CFStringRef here.

auto cfKey = key.createCFString();

Is there an existing constant you can use for this key?

You can't use WTF::String in API; see WKStringRef. This breaks the build (I'm not sure why EWS didn't catch it, but it's failing for other patches now that it's landed).

Thanks for pointing out. Will take a look at that test. Whatever it was checking wasn’t accurate if it was passing before…
