When isVisible changes the markers is didn't hide from the chart

Hi,

In my application I am hiding some of the line chart by changing the visibility. When changing the visibility the markers is not hiding from the chart. Its happening only the mouse pointer is inside the chart before the visibility change. I have created a sample application and created the video recording also. Please check the attached file for example code and video. On the video you can saw that 2 line visibility is changed and line are hidden from the chart and the markers not hiding from the chart.
