Water reflections require direct line of sight to original object

What happened?

Looks like a culling issue. If something blocks your line of sight to an object then the thing you "can't see" will be invisible in water reflections. This is especially noticable when strafing around water that has trees around the shore. I noticed this while using ComplementaryShaders_v4.2.2.

The obstructing leaves carve a chunk out of the mountain's reflection.

This isn’t an iris issue, this is due to the type of reflections most shaders use, SSR (screen space raytracing).
