Using @s only can select player entities, when it should be able to select all entities.

To reproduce:

1. open world in affected version
2. wait for, or place some entities
3. use /data get entity @s[type=minecraft:player]
4. see that you get data relevant to player
5. use /data get entity @s[type=!minecraft:player]
6. game says "No entity was found" even though there are plenty of entities around
