Thanks for the detailed description of the problem; will try to fix this.

Hi I get a similar behavior, even without paste_reference installed. But only if I use a container element.

TYPO3 12.4.16

There is a Bug in EXT:container: b13/container#490 Maybe it has something to do with this issue here.
