  "message": "Synchronously forward chained cancellations (#239)\n\nAdd a test which chains through multiple `.then` calls and then cancels\r\nthe original operation. This test passes with the original code, but\r\nstarts failing after fixing a bug in `Completer.complete` in the SDK.\r\nhttps://dart-review.googlesource.com/c/sdk/+/258929\r\n\r\n- Add a list of extra completers to forward cancellation. In places\r\n  where the cancellation had been forwarded through a `whenComplete`,\r\n  add to the list of extra cancellations instead. This allows the Future\r\n  return by the outer cancellation to wait for the other callbacks to\r\n  complete before firing.\r\n- When setting up forwarding on an already canceled completer,\r\n  immediately forward the cancellation.\r\n- When forwarding cancellations, don\u0027t repeatedly call `_cancel()` on a\r\n  completer which has already been canceled.\r\n- In `race()`, disable cancellation propagation to prevent a cyclic\r\n  cancellation.",
