Collapse and expand sub items with vertical scroll

[psr]

Hi Highcharts Team,

I believe I’ve encountered a possible issue when using collapsible Gantt layers with the yAxis scroll bar.

I was able to reproduce the problem using an example from your site by adding a yAxis scroll bar:

Steps to reproduce:

1- Collapse the last collapsible layer.
2- Scroll down the chart multiple times using the yAxis scroll bar.

Could you please assist me in identifying how to avoid or resolve this issue?

Regards,

try adding a setTimeout function right after collapsing the last layer before using the scroll bar sometimes, there’s a delay in how the layers are collapsing and how the chart redraws, so this could give it just enough time to settle before you start scrolling... It worked for me when I had an issue with a similar setup
