Hi,
Highcharts seems to be not responsive when the chart is located inside a control with style display:table. this only happens when you resize the window width downwards where suddenly the chart area is way over the defined bootstrap columns.
it also seems that chart.containerWidth and reflow width are the same and only change when you increase the window size.
please view: http://jsfiddle.net/onemenny/4x5xzw17/
please advice
