Wrong texture when rendering invisible cube of boats

[GeForceLegend]

What happened?

Almost same as sp614x/optifine#7608. When rendering the invisible cube of boats (vanilla use it to ignore water in boat), Iris will just use the albedo texture of last draw call for current one, which may cause render result changes with other entities, especially in shadow.

Screenshots

2 captures showing shadow inside boats changes while giving player invisible effect, caused by texture used for the invisible cube changed to another one (tho both of them are not boat texture) in shadowmap generating.

A capture showing it's using sheep texture.
