Testing document title: correct example

This page has a single, descriptive <title> element in <head>, unique to this page and matching what's shown in the browser tab.

Expected result: the browser tab should show the title text. Assistive technology should announce it on page load, and again whenever focus returns to this tab (e.g. switching tabs, or returning from another window).

HTML markup
