Context:

The year and month dropdown menus in the datepicker are not usable because the datepicker disappears when clicking on an option from either dropdown.

Steps to reproduce:

1. Create any report type
2. Add a date filter, for example a start date filter or a date variable filter
3. Choose any option that uses a datepicker, eg "between"
4. Click on the month or year to open the dropdown menus
5. Click on any month/year in the dropdown

Observed result:

The datepicker disappears once you click on an option from the dropdowns.

Expected result:

The datepicker should not disappear and the chosen option from the dropdown should be selected.
