Whoever fixes this, might point to https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/ARIA_Techniques/Using_the_alertdialog_role#compatibility from

<p class="summary"><span class="seoSummary">The <a href="https://www.w3.org/TR/wai-aria-1.1/#alert">alert</a> role can be used to tell the user an element has been dynamically updated. Screen readers will instantly start reading out the updated content when the role is added. If the user is expected to close the alert, then the <a href="/en-US/docs/Web/Accessibility/ARIA/Roles/Alertdialog_Role">alertdialog</a> role should be used instead.</span></p>

<li><a href="/en-US/docs/Web/Accessibility/ARIA/Roles/Alertdialog_Role">ARIA: Alertdialog Role</a></li>

until we have a dedicated page.

@chrisdavidmills This also affects https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/ARIA_Techniques#window_roles i.e. https://github.com/mdn/content/blob/main/rfcs/aria-roles.md#unwritten-role-pages has links to pages, that are not dedicated to a single role - shall I update the RFC again?
