Does your Viewport have 2D_HDR enabled?

No, but it's same if 2D HDR enabled.

Is the environment background mode set to Canvas? Remember that the editor renders in its own viewport, so you likely need to assign an environment to it if you want to make the editor itself glow.

I think so. There is an environment node in the main scene and its background mode is set to Canvas.

This only affects the project, not the editor. WorldEnvironment nodes in the editor will
never affect the editor itself by design (outside of the 2D/3D viewport, that is). This occurred in the past due to bugs and it's not exactly behavior that should happen by default again 🙂

See #72343. You can try using RenderingServer.viewport_set_environment_mode() on the editor root viewport RID with the value VIEWPORT_ENVIRONMENT_ENABLED, but this will affect the entire editor rendering and not just your editor plugin. I think the better solution here is to use a Viewport in your edition plugin.
