[CalendarDatePicker][WASM] Using a CalendarDatePicker in a DataGrid column doesn't commit selected date

[jsinsel-kahua]

Current behavior

Set up a DataGrid with a DataGridTemplateColumn that has a CellEditingTemplate as a CalendarDatePicker. When the column is editing, you can open the calendar flyout. However, selecting a date will not commit the value to the cell's data item.

Expected behavior

The date selected in the calendar flyout would be applied to the data item.

How to reproduce it (as minimally and precisely as possible)

Attaching a sample project.
App1.Shared.zip

Workaround

Works on UWP/WinUI

No. Microsoft has a similar bug ticket, but the behavior is different. Their flyout immediately closes whereas Uno lets you pick a date.
