In this test, speculative preloads are made AFTER actual requests are made
(regardless of the change).

Without this change, the speculative preloads are merged to the actual requets
and tracked as preloaded resources.

With this change, the speculative preloads are merged to the actual requets, and
they are not treated as preloaded resources.

         t.done();
