I'm using the Callout control and host a ListBox as content. Basically works as expected. It is possible to select an item in the list and scroll the list with mouse wheel.
Problem is using the scrollbar of the hosted ListBox. When it is used in any way (click, press and move mouse to scroll) the Callout closes. The expected behavior would be that I can scroll the list using the scrollbar and select an item. Callout should stay open till closed by code or focus lost (e.g. click somewhere outside Callout control).
Attached is a small example that shows that behavior.
I tried already to disable autoclose and control (dis)appearance manually. With that approach I have the problem that I don't know how I get informed when there was a click outside Callout control (to close it manually), hence it stays open.
Thanks and Regards
