passenger entity disappears after copy paste operation

[LedariaTim1]

Server Implementation

Paper

Server Version

1.21

Describe the bug

Initial situation: freshly installed Paper 1.21 server with the latest FAWE version (FAWE 2.11.1-SNAPSHOT-858) without any other plugins
when copying a area containing entities which ride entities (as an example a pig with a cow as a passenger) with the command //copy -e and subsequent pasting with //paste -e the upper entity is lost.

And in the console an error is printed.

Duplicate of #2091 but the bug still exists

To Reproduce

create a clean paper 1.21 server and latest FAWE (FAWE 2.11.1-SNAPSHOT-858)
build a flat area
summon an entity with a passenger
/summon cow ~ ~ ~ {NoGravity:1b,Invulnerable:1b,NoAI:1b,Passengers:[{id:"minecraft:pig",NoGravity:1b,Invulnerable:1b,NoAI:1b}]}
select and copy the area with //copy -e
paste it to a free area with //paste -e

Expected behaviour

I would have expected that at the inserted place also the entity with the passenger would be inserted again
