[TF2] Possible regression regarding mat_queue_mode set to -1, or 2 with Control Point, and Bomb holograms' sine proxy

[Whurrhurr]

title. tested with an NVIDIA GPU, would like to see how this looks on non-NVIDIA GPUs. this does not happen in the build of TF2 that SFM uses.
mat_queue_mode 0 gives you this, which has the "sine" proxy in the _dark.vmt for the holograms work, it gives them a little "shimmer" effect.
The VMTs in question (materials/models/effects/robo_marker_dark) use the "Modulate" shader.

 "Sine"
 {
      "Sineperiod" ".3"
      "SineMax" ".7"
      "SineMin" ".6"
      "resultVar" "$alpha"
 }

mat_queue_mode.0.bomb.hologram.mp4

setting mat_queue_mode to -1, or 2 causes the sine proxy to stop functioning.

mat_queue_mode.-1.or.2.bomb.hologram.mp4
