-        This is a workaround for the lack of support for stripes(...) (see

-        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).
