When it's raining, cauldrons fill up with water despite a carpet being placed directly above it.
Steps to Reproduce:
1. Place some cauldrons.
2. Place some carpet directly above the cauldrons.
3. Turn on rain.
4. After about 5 minutes, remove the carpets and some cauldrons will have filled up with water despite carpet being placed above them.
(The process of cauldrons filling up with water as of the result of rain, takes quite a while so I'd recommend setting up multiple cauldrons to speed up the process).
The cauldron fills up with water.
The cauldron should not fill up with water as a block is placed above it.
I have attached four images showing the process of how to reproduce this bug.
I've set up multiple cauldrons as reproducing this with only one can take quite a while.
