<header> descendant of <main>This test case is designed to determine how the <header> element will be announced by various screen readers when it is a descendant of the <main> element.
In this case, the element should not be announced as a banner landmark, as it is not scoped to the <body> element, it is scoped to the <main> element.
By default, the element being tested does not receive focus, so the only way to test how it is announced is via:
<main>
<h4>Other content</h4>
<header>
<h4>Test content</h4>
</header>
</main>
