Without the other patches in this series, this test fails with both with and without Fission enabled, for two different reasons. With Fission disabled, the second reload request appears as empty, due to us being unable to rewind the postData nsIInputStream. With Fission enabled, the second reload request causes crashes due to the nsMIMEInputStream's invariant of requiring a seekable stream is invalidated, causing the nsICloneableInputStream implementation to misbehave.
