I am trying to use joints for simple diagramming tasks.
Recently I noticed my application is broken in IE 11.
After a short investigation it turned out that even the original online demo is broken in IE 11. (missing connecting relationship lines, see attached picture)
Actually the error in my app is more serious, even shapes do not rendered.
All works perfectly in latest Chrome and FF.
Any workaround, or missing I something?
Thanks in advance
