Nit: In comments, just say "null" in lowercase.

Done.

   // |profile| is used for opening urls as well as enabling 'open incognito'.
   // |navigator| is used if |browser| is null, and is provided for testing.
   // |parent| is the parent for newly created nodes if |selection| is empty.
   // |selection| is the nodes the context menu operates on and may be empty.
