Comment (by sergiomdgomes):

 The `for...of` portion of `formdata-polyfill` is only necessary for really
 old Edge versions, pre-18. This means that even the last "old Edge"
 versions should support it, and new Edge is not a problem at all, since
 it's Chromium-based.

 Do we need to support Edge < 18? If not, we should be able to drop
 `formdata-polyfill` entirely: https://developer.mozilla.org/en-
