Hi there,
I can only assume that this is how it would also work in the real world, no? Volumetrics diminish things. You may need to play around to find the right balance between the volume distance and the desired reflection amount. Is the scene to scale? Alternatively, adding a Reflect pass in the multi-pass may help recover your reflections in post.
Hopefully, others may have a workflow that may suit you. ;)
Attached is a basic test.
