[Webkit-unassigned] [Bug 184254] Regression: MessagePort.postMessage() fails to send transferable objects

--- Comment #7 from Tadeu Zagallo <tzagallo at apple.com> ---
It seems that the regression was introduce in https://bugs.webkit.org/show_bug.cgi?id=181922 due to `SerializedScriptValue`s being encoded with `toWireData`, which does not include ArrayBuffers (or any other extra data contained in the serialized value for that matter). However, I'm not sure if this is the best approach, and if it's OK to expose the ArrayBufferContents ctor that I had to expose. Also, we should probably  throw an error when a SharedArrayBuffer is part of transfer list (similar to what Chrome does).
