Describe the issue you are experiencing
The datepicker used in e.g. the "Adjust statistic" developer tool doesn't always work. It usually works the first time it's opened, but after that, nothing happens when I click a date. It's possible to switch to another month view, but selecting a date still doesn't work. It usually helps to close the datepicker and open it again.
Describe the behavior you expected
The datepicker should always work.
Steps to reproduce the issue
- Open the "Adjust statistic" dialog in Developer Tools -> Statistics -> Find an entity with statistics.
- Open the datepicker by clicking on the date.

- Select another date.
- Change the time, maybe open an entry, click "Back"
- Select another date.
- Repeat until a date cannot be selected.
