Bug: Portal gun particles show up in tools mode

[HugoBDesigner]

Describe the bug

When playing P2:CE (or Portal 2) in tools mode, hiding the portal gun does not hide its particles.

To Reproduce

Run the game in -tools mode, open any map with a portal gun in it, fire a portal (to activate the particles), and run r_drawviewmodel 0 on console. It'll appear like this:

Issue Map

Any map.

Expected Behavior

When running the game normally (as in, not in tools mode), the particles don't show up:

Operating System

No response

I think this might be intentional to allow visualization of particles on viewmodel while being worked on. It seems to be added somewhere between ep1 and orangebox.
