HighCharts 饼图获取选定切片周围的框

Question

When rendering my HighChart I sometimes get a blue box around one of the slices. This seems to represent the selected slice. If I use the keyboard arrows the box moves to the other slices. This is how it looks when it renders (sometimes)

And then if this happens I can then use the arrow key to change which slice has the box around it like below

I don't see any reference to this in the documentation for HighCharts or any settings to turn this off. This also only seems to happen when rendering inside of Microsoft.Web.WebView2.WinForms.WebView2 control but I can't be certain. It does not let me cycle through all elements on the control. Once Opera has been selected the next time I hit the right arrow Chrome is selected again so I don't think it's the browser cycling through DOM elements.

Does anyone have any advice on this?

According to the comments - it seems that the issue was related to the accessibility module - https://www.highcharts.com/docs/accessibility/accessibility-module
