Incorrect sorting for translations in container v3.x

[DenisMir]

TYPO3: 13.4.2 (or 12.4.24)
Container: 3.1.1

We recognized incorrect sorting values on translations in free mode (this is important). This problem only exists for container 3.x! (on 2.x it works)

We had a similar issue that was fixed for 2.x in the past: #425. But in this case the reason for the error seems not to be the same.

Here is an example on how to reproduce the error.

• Create a container A
• Nest container B in container A
• Create child element CH1 in container B
• Create child element CH2 in container B (below CH1)
• Nest container C in container A (below container B)
• Create child element CH3 in container C

This results in the database as:

uid	colPos	tx_container_parent	sys_language_uid	sorting	HEADER
8	0	0	0	256	A
9	200	8	0	512	B
10	200	9	0	768	CH1
11	200	9	0	1024	CH2
12	200	8	0	1280	C
13	200	12	0	1536	CH3

Now translate copy (free mode) the page. And you will get in the database:

uid	colPos	tx_container_parent	sys_language_uid	sorting	HEADER
14	0	0	1	1792	A
17	200	14	1	1920	B
18	200	17	1	1984	CH2
19	200	17	1	2016	CH1
15	200	14	1	2048	C
16	200	15	1	2304	CH3

So the sorting of CH1 and CH2 is incorrect now in the translation.

This is how it looks in the backend page module:

Thank you very much for the quick fix.
