Please help me, why does my particle system's "culling mode" not work?

Why the particle doesn’t stopping simulate where the particle “Culling Mode” is “Pause” when it’s offScreen?

I have expected it should be Stoped

the API content is below:

Perhaps because you are looking at it in the Scene View, so it is onscreen?

Sorry for digging up the old post, but I have a question regarding this.
So it is not like typical objects set as Occuludee that culling can be confirmed in the Occlusion - Visualization mode in the scene view, it seems particles are still visible and being played in it even it is out of camera sight in the scene view.

If I want to confirm that the particles are stopped in the out of the sight as well as the other culled objects, is there any way, even as a debug log, or for example a total number of running particles as a stat?
