Change Blob.prototype to global.Blob.prototype

[tmisirpash]

When using Webpack's ProvidePlugin to shim all instances of Blob in the bundle with this polyfill, Webpack will generate a var declaration that looks something like like this:

var Blob = __webpack_require__(203)["Blob"];

// The rest of this polyfill
(function(global)) {

}

If there is already a globally defined Blob, global.Blob will not necessarily be the same as just Blob. The exact error we are seeing is TypeError: Cannot read properties of undefined (reading 'prototype') (which indicates that in this case, Blob is undefined.) We are hitting this because we'd like to start providing Blob as a server-side runtime API, but clients may still be polyfilling with the ProvidePlugin.

Thanks, I'll get this published.
