title: Highcharts: Change hover style in line chart when hovering over legend
body: <p>The default behavior of the line chart is to provide a hover state when hovering over the legend. The hover action also affects the style of the series pertaining to the current legend item. Is there a way to control the styles applied to the series when hovering over the legend?
  I would like to control the width of the series in the chart when the legend is being hovered over.
  Any suggestions?</p>
