It is a bit sad to set it to none while we are initialising it to uninitialised.
Can we change DataTransfer constructor?

Do we have test coverage?

This error seems strange, we got what we expect so why are we failing?

Might be better to use http://{{hosts[alt][]}}:{{ports[http][0]}}
That way we keep cross origin posting which might be useful for the test.

We will need to upload this change to WPT as well.
If you use webkit-patch upload, it might allow you to automate the process and I can merge the changes in WPT.

Yes.  This is what makes the send-file-form-{encoding}.html tests pass.

As noted in the changelog, I think it's expecting === and it is only ==.  I tried tinkering with it for a while, but couldn't get it quite right in a simple patch.
