Sorting issue after workspace publishing

[s2b]

Based on #738, I was able to reproduce an issue with container sorting related to workspaces. This works in TYPO3 v14 with both container 3 and 4. Maybe there are other/simpler ways to achieve this, but this was my approach:

1. Create new page with 1 container and 3 children as well as 3 other content elements below
2. Switch to draft workspace
3. Add one more element inside container
4. Move container to the end of the page
5. Publish only the container element

Now the container in the live workspace has a higher sorting than its children. When one of the outer elements are moved inside the container at the first position, they actually are placed at the last position after a page reload. See also attached screenshots, where I've annotated the sorting values according to the database.

• step 1
• step 2-4
• step 5
• after step 5
