Bug: Auto Portals in sp_a1_intro1 do not render correctly with Volt physics.

[Badpoolinator]

Describe the bug

Volt enabled:

(The cheap titles are not related. I was using host_framerate.)

Volt disabled:

This behaviour only happens in sp_a1_intro1, and only with the pre placed prop_portals. Creating portals with a portal gun will render fine. Tried in sp_a1_intro2, and the portals rendered fine. I also tried it in my own map, this isn't caused by the portals being activated at the same time. I also tried it with lighting, and they rendered fine. This seems to only be a problem in sp_a1_intro1.

Issue Map

sp_a1_intro1

To Reproduce

1. Open sp_a1_intro1
2. Skip the container ride, go straight to the first auto portals.
3. Wait for them to open.
