        This is a workaround for the lack of support for stripes(...) (see
        https://drafts.csswg.org/css-images-4/#stripes).
        The outline should be composed of 1px white, 2px blue and 1px white.
        This could be achieved in different ways:
          - using a linear-gradient;
          - using a box-shadow;
          - using an outline on the selected element and an outline+border on
            the ::before pseudo-element.
        All these options lead to incorrect rendering likely due to rounding
        issues.
        That said it doesn't mean that the current is ideal, but it's the best
        we could come up with for the moment.
        One drawback of this approach is that we use a border on the selected
        element which means that we must take care of it when positioning the
        div in js (see AnnotationEditor._borderLineWidth in editor.js).
