func_documentation_string: Finds all `File` instances in `formData` and creates a new `File` instance whose storage is
  forced to be a `Blob` instead of being backed by a file on disk. That works around a bug in
  Chrome where `File` instances with `has_backing_file` flag cannot be sent over a process
  boundary when site isolation is on.
