Tab order wrong Accessibility Checkpoint

Description

The tab order does not follow logical sequences on the page.

Help

Renumber the tabindex values so the tab order matches the reading order of the content, or remove positive tabindex values entirely and let the tab order follow the document order (using tabindex=0 where needed).
