You render `<NavLink to="/inbox" className={({ isActive }) => isActive ? 'on' : 'off'}>`. The user is at `/inbox/messages/42`. By default (no `end` prop), does this NavLink get the active class, and why?
<NavLink
to="/inbox"
className={({ isActive }) => (isActive ? 'on' : 'off')}
>
Inbox
</NavLink>
// current URL: /inbox/messages/42
