I'd like to implement a highlighting style similar to the default selection style. In that style, if the selection spans multiple lines the border is drawn around the outer edge, not on every line.
When I try to add a border to my HighlightingStyle with:
deletedStyle.BorderBrush = new SolidColorBrush(Color.FromRgb(255, 148, 148));
deletedStyle.BorderStyle = HighlightingStyleLineStyle.Solid;
I get a border around every line, not just the outer edge.
