function isUnlabeledInputImg(element) {
      return (
        element.name === 'input' &&
        element.attribs.type === 'image' &&

        !isHiddenFromScreenReader(element) &&
        !elementHasAttribute(element, 'alt')
      );
    }
Is the element an `<input type="image">` with no `alt` attribute?
