Bug in easychart legend / marquee mode / point mode

In the list of pen, I put some html to have pen’s legend splitted in multiple line.

In point mode the tooltip is OK (if I suppress html tag with getXtraceLable extension function)


In maquee mode the tooltip is not OK : (html tag are visible !) (no extension function)


If I use \n it’s OK for the legen, but not for both tooltips Marquee or point mode !

How to archive multiple lines text for legend with a ggod display for tooltips ???
