Submenu closes while focus is on parent link

Description

The Interactivity API for the Navigation block closes the submenu of a parent when focus remains on the parent. Without the Interactivity API, the submenu will remain open while focus is on the parent link.

Step-by-step reproduction instructions

1. Have a navigation with a submenu
2. Go to the frontend of the site
3. Use the keyboard to place focus on the submenu chevron icon
4. Press enter to open the submenu
5. Press shift + tab to return focus to the parent link

Without the Interactivity API, the submenu remains open when focus is on the parent link.
