      Description

      The bug

      When using /data modify to append the entries of a list into another list, they get appended in reverse order.

      How to reproduce

      /setblock ~ ~ ~ minecraft:chest{Items:[{id:"minecraft:stone",Count:1b,tag:{list1:[1,2,3],list2:[1,2,3]}}]}
      /data modify block ~ ~ ~ Items[0].tag.list1 append from block ~ ~ ~ Items[0].tag.list2[]
      /data get block ~ ~ ~ Items[0].tag
      

      This results in the list [1,2,3,3,2,1] rather than the expected list [1,2,3,1,2,3]
