TYPO3 Core

Description:
Tested with TYPO3 9.5.22

We have observed that not all changes made on a page in the workspace (e.g. creating, moving, editing etc.) were recorded as changes in the regular workspaces module (WEB - Workspaces). The workspace module simply remained empty for this page, but the page was marked as "edited" (yellow) in the page tree - which is correct, because it was edited.

We do not know what causes this issue. It cannot always be reproduced.

In an emergency, the idea came up to undo the unwanted adjustments in the workspace via the workspace page history. However, this had unwanted effects on the LIVE version of the site, here elements were suddenly missing.

Example:
We edited the page "Showcase" in the workspace: we added a regular "Text and Images"-element.
The page is marked as edited in the pagetree (yellow highlight).
We switch to the workspace module (WEB - Workspaces) and see no changes for "this page" - the module is empty, although the page was edited.
We are not able to undo or deploy the changes easily.

Question:
Why are some changes not recorded in the workspaces module (WEB - Workspaces), does one have to pay attention to something special?
Why does editing the page history in the workspace affect the live version?
Can the regular page history function in the workspace be deactivated?
