The underside of water reflects what is below it when RTX/ray tracing is enabled

Searched bugs for "RTX water". 

In Minecraft with RTX, the underside of the air/water interface reflects what is below it. This is disorienting, since it is not how water reflects in reality. 

Of course, water in Minecraft does a lot of things that real world physics does not abide. So maybe it's not an issue.
