When you place blocks with BlockEntityTag in survival, the blocks lose them.
Then, why are we allowed to edit survival spawners with eggs ?
Sometimes also the spawner changes but forgets to change the "SpawnData".
For example, we have a zombie spawner, we right-click with a creeper egg, it becomes a creeper spawn and becomes a zombie spawner again:

Spawner:
data: {MaxNearbyEntities: 6s, RequiredPlayerRange: 16s, SpawnCount: 4s, SpawnData: {id: "minecraft:creeper"}, MaxSpawnDelay: 800s, Delay: 0s, x: 328, y: 63, z: 2778, id: "minecraft:mob_spawner", SpawnRange: 4s, MinSpawnDelay: 200s, SpawnPotentials: [{Entity: {id: "minecraft:creeper"}, Weight: 1}]}
Spawner after clicking once with the cow spawn egg:
data: {MaxNearbyEntities: 6s, RequiredPlayerRange: 16s, SpawnCount: 4s, SpawnData: {id: "minecraft:creeper"}, MaxSpawnDelay: 800s, Delay: 441s, x: 328, y: 63, z: 2778, id: "minecraft:mob_spawner", SpawnRange: 4s, MinSpawnDelay: 200s, SpawnPotentials: [{Entity: {id: "minecraft:creeper"}, Weight: 1}]}
Spawner after clicking for the second time with cow spawn egg:
data: {MaxNearbyEntities: 6s, RequiredPlayerRange: 16s, SpawnCount: 4s, SpawnData: {id: "minecraft:cow"}, MaxSpawnDelay: 800s, Delay: 384s, x: 328, y: 63, z: 2778, id: "minecraft:mob_spawner", SpawnRange: 4s, MinSpawnDelay: 200s, SpawnPotentials: [{Entity: {id: "minecraft:cow"}, Weight: 1}]}
This is also a problem because many people use spawn eggs in their datapacks to create new creations.
To solve his problems, the players in survival have to be unable to modify the spawners anymore.
