With the CMS 4.12 update functionality was altered to utilise an Extension to obtain the CMS Edit link for a page, rather than having SiteTree do it internally. Unfortunately the default return case for `extend` (see Extensible) is an _empty_ array. This leave code potentially referencing an array offset that doesn't exist ([0]). PHP 8 is less forgiving that it's predecessors on this kind of behaviour. We should check that the responses from extensions exist before trying to reference them.
