Using highcharts, if you create a pie chart with styledMode: true;
and you import their highcharts.css file, the hover effect on legend items causes all legend items to go opaque.
You can even see this on their demo page by selecting the Styled Mode: Pie.
And then hovering over the legends items. If you set the styledMode: false;
and then remove the CSS import it goes away.
My question basically: Is this a bug? It seems like unintended behaviour.
