WebDatePicker Calendar does not hide after date selected

2020R1 Web 2.0 Windows 10
I am using the new WebDatePicker, can someone explain how to make the datepicker calendar go away once a date is selected, without having to tab or click outside of the datepicker calendar. I have tried several things in the valuechanged event but nothing seems to work to hide the calendar.

That sounds like a bug to me. Please report it via Feedback then send me the case number.

I have the same problem with xojo 2020 release 2 on OSX

any solution?
