Old StackLabels does not disappear bug on resizing window or when used with highstock scrollbar

[kishan-sanghani]

Stacklabels does not seem to remove the old stack label values from the column charts when you resize your browser or when you use highstock.js to enable scrollbar.

Here is the link of stack labels with highcharts:

For the first time it is proper. but when you resize the window old stack labels does not disappear causing multiple stacklabels.

Example with highstock.js to activate scrollbar
