Hello,

Actually, we came to the conclusion that it’s not a bug - Webix needs to focus dropdown calendars to maintain keyboard navigation and accessibility.

So you can either use the validateEvent:"change" for Datepicker control,
on define a custom onBlur handler which will start validation depending on the next focus target: Code Snippet
