HDRP underwater volumetric rendering issue

[Danon5]

If you put a volumetric light under the water and crank up the volumetric multiplier so you can see it properly, the volumetrics will only appear on fragments that have a reasonable depth (i.e. when there are some objects behind the light). So, if you have no objects in your scene and do what I just described, no volumetric light will show at all. Is there a quick way around this?

This is a light that has some terrain behind it. The volumetrics appear properly.

This is that same light, but with the terrain hidden. The volumetrics are completely invisible.

I am using the default Fullscreen mode on the underwater renderer component.
