[Bug] Signals do not render through stained/tinted glass copycats

[piggypiggyyoinkyoink]

Describe the bug
Nixie tubes or semaphores on signals do not render when looked at through a stained or tinted glass window made using copycat blocks on an assembled train. Regular glass behaves as expected.

To Reproduce
Steps to reproduce the behaviour:

1. Build a train that has a window with Stained or Tinted glass inside Copycat Blocks
2. Assemble the train
3. Build a signal using either Nixie Tubes (or the Semaphore from S+R)
4. Look at the signal from inside the train through the window

Expected behavior
The nixie tube or semaphore is visible through the window

Actual bahviour
The nixie tubes/semaphore do not render.

• Mod Version: 3.0.4

Additional context
With regular glass it works as expected (1st screenshot) however with tinted or stained glass (2nd screenshot) the nixie tubes do not render. The same happens if I use the semaphore signals from Steam n Rails. I am not using any performance mods (sodium, betterfps etc) or shaders/resourcepacks.
