Re: [w3c/FileAPI] Correct handling of resizable ArrayBuffer? (Issue #219)

guybedford left a comment (w3c/FileAPI#219)

I discussed whether this is expected to throw briefly with @syg and he seemed to indicate that if the implementations are able to support it correctly there is no reason the spec couldn't be changed to add the support.

For Wasm toolchains wanting to use resizable buffers by default, the use case would be passing a view into linear memory that is a temporary borrow of a linear memory view, where the Blob constructor already does a copy so it would be wasteful to have to do two copies instead.
