If you look through glass or water, you can see clouds that are further away than what your actual render distance is, which is trippy, because without glass (normally looking at them) you can't see any clouds.

Steps to re-produce:
1. Create a World
2. Turn Ray tracing on
3. Place some Glass around
4. Look at Clouds through Glass
5. Also look at clouds/around in sky directly without Glass
6. Compare

Expected results: Clouds out of your render distance can not be seen

Observed results: You can see clouds far far away from what your render distance is.

Screenshots: (in this case my render distance is 16 Chunks)
Through Glass:

Same scene without glass: (the clouds further away are no longer seen)

Example with water (for water I recommend having some water floating in air, as It's hard to observe clouds if water is on ground):

happens even with hand-held glass:
