TYPO3 Core

In the "GroupResolver" method "resolveGroupsForUser", we only fetch groups recursively before the event "AfterGroupdResolvedEvent".

It has the consequence of any groups added afterwards, will not have any subgroups fetched.

$resolvedGroups = $this->fetchGroupsRecursive($originalGroupIds);
$event = $this->eventDispatcher->dispatch(new AfterGroupsResolvedEvent($sourceTable, $resolvedGroups, $originalGroupIds, $userRecord));

We could redo the fetching afterwards, to ensure all groups are loaded recursively

$resolvedGroups = $this->fetchGroupsRecursive($originalGroupIds);
$event = $this->eventDispatcher->dispatch(new AfterGroupsResolvedEvent($sourceTable, $resolvedGroups, $originalGroupIds, $userRecord));
$resolvedGroupsAfterEvent = $this->fetchGroupsRecursive(array_map(fn(array $group) => $group['uid'], $event->getGroups()));
