The Warden, despite having tendrils on its head like a sculk sensor, doesn't detect all vibrations that sculk sensor does. The following vibrations are as follows:
Explosions (such as TNT)
Piston extends and retracts
Flying mobs (such as bats and bees)
Tripwire sets, activated and detached
Placing water/lava/powder snow into the cauldron
Dispenser activating successfully and fails to dispense
How to Reproduce
Spawn a warden with nametags (so it doesn't despawn)
Test some of the vibrations I listed (must be tested in survival for reliable result)
Observed Result
The warden didn't detect the vibration
Expected Result
The warden detects the vibration
Still affects 1.19.80.23 as the Warden still doesn't detect vibration from bees flaping its wings
