Bug: The playermodel is invisible in func_monitor entities unless third person is turned on

[3kotyx]

Describe the bug

You cannot see yourself (your own playermodel) in the Monitors ("func_monitors"), UNLESS third person is turned on. In third person it all works perfectly fine. However, when viewing this in first-person, the playermodel is invisible to the camera.

To Reproduce

1. Compile the VMF attached in the "Issue Map" section and run it ingame.
2. Look at the monitor
3. Notice lack of the Player model
4. That's it.

Issue Map

Compile it and run ingame on regular P2CE. You WILL NOT be able to see Chell on the monitor even though the camera is pointing at the player.

Expected Behavior

When the camera is enabled, I expected the player to be visible on the montior, just like World Portals show the player through them.

Operating System

Windows 11 | 64-Bit
