repro steps:
1) in any kanban view that is not grouped, use the arrow key to focus the last card
2) use the up key to focus the previous card
3) use the TAB key to focus any element inside that card
4) use the down key to try to navigate to the last card -> traceback
The error comes from the fact that `focusNextCard` assumes that the
focus is exactly on the card element and not on any of its children.
