Anchor tags not working on "Enable clean URLs" page

Anchor tags not working on https://www.drupal.org/docs/7/configuring-clean-urls/enable-clean-urls page.

When I go to https://www.drupal.org/docs/7/configuring-clean-urls/enable-clean-urls and I click on an item in the “On this page:” list like General information (https://www.drupal.org/docs/7/configuring-clean-urls/enable-clean-urls#g… ) or Fixing problems (https://www.drupal.org/docs/7/configuring-clean-urls/enable-clean-urls#p… ), I expect it to jump to that point on the page. It doesn’t.
