Request Description

Relates to #2935.

For solid blocks, the inner faces of fluids typically are not rendered.

There are, however, exceptions such as glass: while the top and four side faces will not have the fluid render against them, the bottom face will. This is inconsistent with many opaque blocks.

The behaviour should ideally be consistent: either fluid faces wouldn't render against any of glass's faces, or they should render against all of them. The former behaviour appears to be preferable.

Solving this issue seems tricky, however, without special-casing certain block IDs or introducing behaviour with the potential of causing equivalent or larger incongruences.
