Before this patch, when Datetimepicker is selected, it expands from the top, so it was impossible to scroll and hence the user cannot select the date.
Now, after applying this patch, the Datetimepicker will expand to bottom and the subgrid will be scrollable, so the user can easily select the date time and other options as well.
When a user tries to select start and end time using the calendar, the calendar gets hidden and inaccessible to the user.
Solution:
Set `Backform.DatetimepickerControl` option `widget positioning > vertical` to `bottom` which ensures Datepicker widget expands to bottom whenever it is opened.
