            Bug ID: 177647
           Summary: FormData does not post the content of new File()
           Product: WebKit
           Version: Safari 11
          Hardware: Macintosh
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Forms
          Assignee: webkit-unassigned at lists.webkit.org

The following code does not post the content of the file object to the server in Safari 10 and Safari 11. 

var fd = new FormData();
fd.append('test', new File(['hello world], "test.txt"));

jQuery.ajax({
  url: 'https://example.com',
  type: 'POST',
  data: fd,
  contentType: false,
  processData: false
});

The following works fine in Safari 10 and 11:

var fd = new FormData();
fd.append('test', new Blob(['hello world]), "test.txt");

jQuery.ajax({
  url: 'https://example.com',
  type: 'POST',
  data: fd,
  contentType: false,
  processData: false
});

I think it should work with the new File too as it works in Chrome and Firefox.
