Tokens for Send an order email action Sender field

In uc_order_action_email(), token replacement is done on $settings['from'], but the result ($addresses) is overwritten and therefore never used.

  // Apply token replacements to from and recipient e-mail addressses.
  $addresses = token_replace_multiple($settings['from'], $settings['replacements']);
  $addresses = token_replace_multiple($settings['addresses'], $settings['replacements']);

Were tokens truly intended to be supported for this field?
