What problem does this address?

When you create a navigation using the core/navigation block you often want to add a link to Home. It's great that we supply a "Home link" block for this purpose.

However, whilst normal Nav Link blocks output a current-menu-item class when you are on that page, the Home link block does not. This makes it impossible to style the current page consistently across the navigation.

What is your proposed solution?

The home link block should output the current-menu-item class when you are on that page. It should mirror the same functionality as the core/navigation-link block.
