Ensure all of the new navigation is covered in tests.

Similar to MDL-70221 This issue should ideally require no extra work from within the team, The idea is that once all of the new features are rolled together we run the entire Moodle testing framework to ensure existing tests continue to pass and any new applicable tests pass.

If this issue requires no work then it may be manually closed after testing.

Acceptance criteria

• Behat & PHPUnit tests continue to pass across platforms & themes
