Wrong sorting by pasting between nested containers.

[tlayh]

Hi,

I have some issues with copy and paste between nested containers. The sorting is wrong, and the element gets always attached at the bottom.

Setup:
TYPO3 Vanilla (12.4.27) with ddev. Only b13/container_example (2.0.0) and b13/container (master or 3.1.5) are installed.

Scenario:

• Target Page: Using the 2column from b13/container_example and put another 2column in the first column
• Source Page: A single regular text element

If I now copy the text element from the source page and paste it into the target page above the inner 2column element, it is always added at the bottom.

I added a short screen recording where you can see what exactly I am doing.

Screencast-CopyPasteSorting.mov

I changed some code like shown in the draft pull request:
#597

This fixes the issue, but the method is also used in other places. I was not able to figure out the correct solution.

Best regards,
Thomas
