Note that this is not the grid going into the distance.

This isn't a bug per se. The horizon color was never exposed to this menu since the menu is just intended for quick edits to the overall color of the scene. That's also why it only exposes a few options from the WorldEnvironment.

@clayjohn I would argue that at the very least this is really surprising. I found this issue while doing my new hobby of "watching random Godot streamers", and one of them was trying to setup an editor environment they could use to test their particle system.

It looked like a reasonable thing to want to do to me.

Sure. I'm just providing context so no one goes investigating to find the root of the bug.
