Describe the bug
In some situations, when copying a page, its attachments get lost.

To Reproduce
Steps to reproduce the behavior:

1. Create a page and add some images
2. Copy the page via "Copy or move" page action
3. Open the new page
4. See that images/attachments are missing

Server details:

• Collectives app version: 2.16.3

For some reason NodeCopiedEvent doesn't fire when copying a collectives page even though it should fire here:

collectives/lib/Service/PageService.php

Line 739 in 8e01951

$newNode = $node->copy($newFolder->getPath() . '/' . $newFileName . $suffix);

When copying a page via Files app, the event fires. There, the copy is done via WebDAV instead of running $node->copy().

I am affected by this bug. Will the fix repair previously copy/pasted pages ?
I have been slowly repairing things, but i have a lot of files not displayed.

Unfortunately not. We're in the process of developing a fix (nextcloud/server#52996), but that will only have an effect on copied pages after the fix was applied.
