This is going to allow `SharedWorker`, right? Or is it blocked in some other
way?

Let's make sure we're still failing the `SharedWorker` test we're failing today
until you get `data:` working for `SharedWorker` as well.

SharedWorker tests were still failing because (similar to Worker) they could not
make the Cross Origin Request to retrieve the resource from the URL.
Fixed in patch 4.

         "Script at '" + scriptURL.elidedString() +
