Codex:

Adds the Navigation block state class to inner list containers.

State block support adds the generated wp-states-* class to the outer block wrapper. The Navigation block renders its menu items inside an inner wp-block-navigation__container list, so the same state class is also needed there for state styles to apply directly to the menu list. Currently this is required as a workaround because of how difficult it is for nav child blocks to inherit styles through the complex responsive nav block html. The bug in https://github.com/WordPress/gutenberg/issues/62690 also prevents inheritance.
