Missing write of data during redirect?

[pbelbin]

For the async initial case, between the doRequest and request.end there is a conditional .write(data). XMLHttpRequest.ts:649 - 656

However, when there is a redirect, and a new doRequest is sent, it appears that the conditional .write(data) is absent before the request.end. XMLHttpRequest.ts:612-613

So it seems that if the data is needed, and it's a redirect scenario, that this will not pass the intended payload data.
