Water behind transparent players doesn't render

Basically the title. The water behind transparent (not invisible) players (e.g. players in spectator) should render, but instead, it does not. Imagines shall be attached soon

Steps to reproduce:

1.  Grab a pool of water and a friend in spectator
2.  While looking at the water in spectator mode, tell your friend to walk in front of you.
3. Observe

What is supposed to happen: You can still see the water

What happens: The water behind your friend stops rendering
