Automatically Expand the Parent NavItem of the highlighted child NavItem

[sxp267]

Describe your motivation

I've a subNavItem and when I click that, it is highlighted which is good. But when I directly hit the subNavItem address in the URL, it is not. I do not see the parent also getting highlighted. Is this a bug ?

Describe the solution you'd like

Parent navItem should expand automatically and show the child item highlighted. In the business app, it is how it is https://labs.vaadin.com/business/accountants
