A recent update from Mullvad Leta introduced the img_elem. This update
broke the existing logic. Now, by checking the length of the dom_result
to see if it was included in the return results, we can handle the logic
accordingly.
If the flag icon is first, it prevents easily searching the select list on the
keyboard. By moving the icon fully to the right, this will enable a user to
search the select list.
