I believe it should probably be:

"(#.URL || #.webkitURL).createObjectURL(#)", window, window,
blob_OR_source_OR_stream)

That doesn't seem to work.  It generates this code (which fails the test):

      t2 = window;
      t3 = window;
      url0 = (t2.URL || t3.webkitURL).createObjectURL(t1);

Also, the implementation of window is:

Window get window => JS('Window', 'window');

In a Web Worker, "self" refers to a WorkerGlobalScope which is either a
DedicatedWorkerGlobalScope or a SharedWorkerGlobalScope.  In normal JavaScript,
self===window.
