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

1. Spawn a warden with nametags (so it doesn't despawn)
2. 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
