Success Criteria: https://www.w3.org/WAI/WCAG21/Understanding/focus-order

In all drawers, the keyboard focus is trapped within the modal in both directions except for the navigation drawer, Here, the focus is trapped when tabbing forward, but when tabbing backward (Shift+Tab) the focus moves into the page behind the drawer.

(Note that the inverse view of the navigation drawer does trap the focus in both directions.)

Ensure that the keyboard focus remains trapped within the navigation drawer when users press Shift+Tab to move the focus backward.
