TCAM:N relation -> leave record with unsaved changes redirects to list instead to create wizard
changing items on a TCA m:n table relation and then trying to add create new items from a specfic type (the "+" button) will show the modal "you are leaving the page with unsaved changes". If you click "save and close" you expect to go to the wizard which will enable you to create a new item. you will get redirect to the list view instead.
I've shot a video which I think can describe this better
Possibly related to https://forge.typo3.org/issues/88875, however I have not yet tried the fix.
