Volume not rendering after render settings or viewport shading modified

The world volume isn't rendering after render settings or viewport shading has been modified. To see the volume I have to update the world volume settings

Can you post a test scene ? I'm not sure to understand the problem.

I just made a scene and was able to replicate the problem. But after saving and reopening the same scene I was unable to replicate the issue.
I tested it again with a new scene and the bug is there but not after saving and reopening the scene. This might make it difficult to share a repro scene.

hopefully this screen capture helps. I noticed changing selection in the viewport is enough to get the volume to render again.
Basically if i change a render setting the volume is no longer rendered in the viewport. If modify the volume or change my selection in the viewport the volume will "come back" and render. I would expect the volume to always be rendering as I change render settings
