Focus Movement for Keyboard navigation

Hi,

We are using version 6.1.2 for Kanban. We are observing an issue for focus movement.
When we press tab key, at first, the header in first lane gets focus. On next tab press, the list (webix_kanban_list) gets the focus and not the first card.

Is there any way we can change the focus to first card instead of list?

Regards,
Pravin
