+  1. Assert: _stream_.[[state]] is `"erroring"`.
+  1. Assert: ! WritableStreamHasOperationMarkedInFlight(_stream_) is *false*.
+  1. Set _stream_.[[state]] to `"errored"`.
+  1. Perform ! _stream_.[[writableStreamController]].[[ErrorSteps]]().
+  1. Let _storedError_ by _stream_.[[storedError]];
+  1. Repeat for each _writeRequest_ that is an element of _stream_.[[writeRequests]],
+    1. <a>Reject</a> _writeRequest_ with _storedError_.
+  1. Set _stream_.[[writeRequest]] to an empty List.
+  1. if _stream_.[[pendingAbortRequest]] is *undefined*,
+    1. Perform !  WritableStreamRejectCloseAndClosedPromiseIfNeeded(_stream_).
+    1. Return.
+  1. Let _abortRequest_ by _stream_.[[pendingAbortRequest]].
