Just catching up with this thread. We ran into the same problem last week while
investigating FormData and XHR. Since FormData is designed to allow XHR to interact
with existing form end-points that usually required a navigation, we've found that
few of them have been tested with empty filenames.

I was about to send a similar proposal. We'd prefer to add an optional argument
to append that specifies the filename. This is the smallest change to
implementations and doesn't require developers to understand the BlobBuilder in
order to use FormData. Having to create another reference to a Blob and probably
deal with managing a File and Blob both pointing to the same data seems
unnecessarily involved when all we want is to get the filename into the FormData
object.

Yes, the blob has a content type so the correct type can also be sent.
