Revision page shows two identical local tasks

I'm taking a look

So this seems to be a bug outside of l10n. I found that one of the incidents is being added via the Group module, still haven't found what's responsible for the other, most likely it's part of a core function. Anyway, I'm closing this issue, it's not part of l10n_server.

The Group module seems to add another Revision local task in group.link.tasks.yml, creating a duplicate task in the Primary Tabs.

Seems like it's due to core changes.

One is defined in the group module links.task.yml, the other is coming from the VersionHistoryLocalTasks deriver due to the presence of a version-history link template in the group entity.

Check also the note in node.module node_local_tasks_alter.

So apparently this is going to be handled by core in the future and group's local task can be removed.

This issue is also reported in 🐛 Drupal 10.1: Revisions tab appears twice on Groups Needs review . I'll close this issue as a duplicate as the other issue has a more elaborate issue summary and a patch that fixes the issue.
