Set content-length header of FormData requests?

[olalonde]

I went through the standard and could not figure out if there was a way to set the content-length of a fetch POST request with FormData as the body. Is that intentional? If not, it would be useful for fetch to automatically set the content-length header as it does for content-type.

This happens in step 5 of https://fetch.spec.whatwg.org/#concept-http-network-or-cache-fetch.

Oops, right. Missed that for some reason.
