Warden ignores whether the place it appears has a block above

The Bug

No description.

It would be very funny that a Warden appears when it finds that it's stuck in a Deepslate-material block…

How to produce

1. /setblock 0 0 0 minecraft:bedrock
2. /fill 0 3 0 ~ 255 ~ minecraft:bedrock replace
3. Place a Sculk Shrieker nearby
4. Put a Sculk Sensor and attempt to active Shrieker, then immedietly destroy Sensor when Shrieker is shrieking in case Warden appears on Sensor
5. Observe
