The part of the portal that is underwater is not rendering the other side with BSL Shaders.

Describe the issue that you encountered

When I put BSL enabled, the portal does not render the other side of the portal underwater. Is it BSL's fault or ImmPtl one ?
Also, there's a tiny thing that I don't know if it is a bug or a feature:

There is a tiny line that indicate that there's a portal (not intentionnaly for sure), is there a way to stop it from appearing ? (This bug work with only ImmPtl and Sodium)
PS: I posted that report in the issues before knowing that we need to put it in discussions, sorry to have it x2.
