Bug: Laser beam misbehaves when a portal is placed behind its emitter

[iamsirenstorm]

Describe the bug

Laser beam misbehaves when a portal is directly behind the emitter. The laser beam coming out from the paired portal is offset, causing it to "magically float" in the air.

This also breaks interactions with the reflector cube when attempting to redirect the laser being cast by the emitter. Redirecting the laser coming out of the paired portal works as intended (The cube must actually be hit by the laser. Nothing changes if the cube is sitting within the offset gap).

Issue Map

Applicable to any map with the right level setup to allow this to happen. Seems related to a handful of other Laser + Portal (or Schrodinger Cube) issues, but not confirmed. Attached a test map for this interaction.

To Reproduce

1. Open a relevant map (for this scenario, a map that allows you to place a portal behind a laser emitter), or the attached test map.
2. Place a portal behind the laser emitter.
3. Place the other portal anywhere else (but not directly where the laser emitter is pointing to).
