The result of /seed does not get properly stored using /execute store

The bug

When /execute store is used to store the result of the /seed command, the wrong value gets stored. Here are some values I found:

• If the seed is 225704178974273007, the stored value is 1142238703.
• If the seed is -8136237196898536299, the stored value is -2037713771
• If the seed is -6529837547381228143, the stored value is -480936559

How to reproduce

1. Create a new world, or load an existing world
2. Type /seed to obtain the world seed.
3. Create a scoreboard objective to store the seed in.
   /scoreboard objectives add seed dummy
   /scoreboard objectives setdisplay sidebar seed
4. Run the following command to store the world seed in the scoreboard data:
   /execute store result score @s seed run seed
5. Note that the stored value is different from the actual seed.
6. Give yourself an item with a custom NBT tag.
   /give @s minecraft:stone{seed:1}
7. Drop the item on the ground.
8. Run the following command to store the world seed in the item data:
   /execute store result entity @e[type=item,limit=1] Item.tag.seed int 1 run seed
9. Get the entity data and note that the stored value different is from the world seed, but the same as the one stored in the scoreboard objective.
   /data get entity @e[type=item,limit=1]
