RE: web.dev managed focus and WCAG

That page is describing a best practice that only applies in specific circumstances. Not following it does not constitute a WCAG non-conformance.

If your website is not a single-page application, the “best practice” doesn’t apply at all. In fact, you would need to advise users of the change of focus in advance otherwise you may violate SC 3.2.2 (On Input), because the change of focus constitutes a change of context.

Subject: web.dev managed focus and WCAG

The Lighthouse accessibility report lists the following between the items to be checked manually:

  *   The user's focus is directed to new content added to the page ( https://web.dev/managed-focus/ )
While the meaning and the importance of this item are clear to me, I'm not sure which WCAG 2.1 criterion, if any, could be met by following this suggestion. web.dev<http://web.dev> gives no links, and while the other items in the list can be easily linked to a WCAG 2.1 criterion, I have doubts on this one.

Can someone help? Thanks in advance :)
