Mobs no longer spawn from spawner if the monster spawner gets waterlogged

Yesterday when I was making an xp farm in a dungeon, I accidentally waterlogged the spawner and the mobs no longer spawn, even after removing the water. The spinning mob in the spawner is also gone

Step to reproduce:

1. Place a spawner and put a mob to spawn in spawner
2. Check if the mob spawns
3. If it does, then waterlog it and remove the water

Expected results:

The mobs will still spawn

Observed results:

The mobs will no longer spawn
