Description Andreu Botella 2020-11-18 07:07:48 PST

The fact that you can create a FormData object from a form and observe its entry list, and the fact that you can construct a FormData object from scratch and build a multipart/form-data payload from it, means that the newline normalization in "append an entry" (https://html.spec.whatwg.org/multipage/form-control-infrastructure.html#append-an-entry) can no longer be deferred to the time when the form payload is constructed, as WebKit seems to be doing.

This is now being reconsidered in the specs: https://github.com/whatwg/html/issues/6469

Comment 3 Andreu Botella 2021-05-21 05:33:22 PDT

Now that https://github.com/whatwg/html/pull/6624 is merged, the HTML spec's behavior now matches WebKit's (except for bug 225299), so I'm closing this bug.
