Wrong selected item in navigation sidebar

Docs or angular.io Bug Report

Description

When you click on Understanding Angular — Components — Sharing data between child and parent directives and components in navigation sidebar, another item gets selected: Understanding Angular — Templates — Inputs and Outputs. Both of them are linked to the same page. Should the item highlighting logic be re-designed or is there any error?
