Description

The new "Page List" block which you can insert in the Navigtion block to have page menus stay in sync with content created, is missing CSS classes for current pages or page ancestors.

Step-by-step reproduction instructions

The easiest way to see CSS classes traditionally applied to menu items, is to use a non-block based theme, such as Twenty Twenty One.

Create a menu in the menu screen, with submenu items.

• Navigate to a page in menu. Observe that it has CSS classes such as these: menu-item menu-item-type-post_type menu-item-object-page menu-item-home current-menu-item page_item page-item-451 current_page_item menu-item-1172
• Navigate to a subpage in a menu. Observe it has classes such as these: menu-item menu-item-type-post_type menu-item-object-page current-page-ancestor current-menu-ancestor current-menu-parent current-page-parent current_page_parent current_page_ancestor menu-item-has-children menu-item-1171

Expected behaviour

Similar CSS classes, or at least a subset, would be nice to have for the Page List block, so that active menu items can be styled. Here in TwentyTwentyOne, the "Home" item is the current page:

Probably a subset of CSS classes would make for an excellent start, and then additional classes could be added as necessary. For a current page item, probably current-menu-item would be plenty, and for a menu item that has a subpage active, current-menu-ancestor would be great.
