Problem/Motivation
Parent issue: #3090200
This is interesting issue at Comment#25, let me talk something.
Paragraph permission flow on Layout builder: Paragraph -> Block Content -> Inline Block -> Node
(Inline Block just contacted Block Content and Node)
After Node revert, the [Block Content] on Node Layout also revert to old revision.
But on \Drupal\paragraphs\Entity\Paragraph::getParentEntity(), it always get the new [Block Content] revision.
On Drupal\layout_builder\EventSubscriber\SetInlineBlockDependency::isBlockRevisionUsedInEntity(), it want to match [Block Content] revision.
But on Node, [Block Content] is old, Paragraph provided is new, cannot match, so no permission on Paragraph.
Steps to reproduce
- Prepare a Block Type with paragraph.
- Create a content.
- Add a Inline Block on Layout, save.
- Go back to Layout, edit the Inline Block above, save.
- Goto Revisions, revert revision to created at Step 2 .
- Goto Layout, the Inline Block content was missiong, and the Paragraph permission was missing.
Proposed resolution
Root resolution:
- Paragraph add parent_revision filed to get parent entity by revision_id. (But this need Paragraph team support and have old data problem)
Temporary solution:
- Judge Block id used in entity at \Drupal\layout_builder\EventSubscriber\SetInlineBlockDependency
