Chromium's implementations of Web Bluetooth and WebUSB currently throw a non-standard InvalidStateError when passed an ArrayBuffer or TypedArray which has been detached (e.g. by calling transfer() or using postMessage() to send the buffer through a MessagePort).
I will be changing these APIs to follow the "get a copy of the bytes held by the buffer source <https://webidl.spec.whatwg.org/#dfn-get-buffer-source-copy>" algorithm and treat a detached buffer as an empty byte sequence. I expect this will not have any web compatibility impact because it is a programming error to pass a detached buffer to these APIs, which is why we added the exception to begin with. This change makes the APIs consistent with other buffer-consuming APIs like Web Serial and WebHID, where we handle this case with the specified behavior.
