Changing the svg desc tag content using highcharts wrap extend.
Highgarts.wrap(Highcharts.SVGRenderer.proptype, "init", function(proceed) {proceed.apply(this, Array.prototype.slice.call(arguments,1);this.box.children[0].innerHTML= "my content";})
Which is working in 11.2.0 version but it is not working in latest version. Please help me out resolving this.
