Comment (by desrosj):

 Thanks @sergiomdgomes!

 When I originally investigating, I referenced the
 compatibility-as-of-2020-01-13 native browser compatibility section in the
 polyfill's Readme file]. This indicates that no versions Edge support

 However, I just did some more digging and it seems that this is
 [https://caniuse.com/mdn-javascript_statements_for_of incorrect according
 to Can I use].

 With this in mind, I think that we can also stop loading the `formdata-
 polyfill`. I'll update the PR.
