Effect plugins using PF_OutFlag2_I_USE_3D_CAMERA fail to receive PF_Cmd_SMART_PRE_RENDER/PF_Cmd_SMART_RENDER events when the camera layer begins at a non-zero frame

I have effect plugin that use the PF_OutFlag2_I_USE_3D_CAMERA flag. 

In the After Effects project I have such setup:

  • Camera layer starts at composition frame 10 and have duration of 30 frames
  • My effect layer also starts at composition frame 10 and have duration of 30 frames

When I select composition frame in the range 10-20 and change the camera transform, my effect does not receive PF_Cmd_SMART_PRE_RENDER/PF_Cmd_SMART_RENDER events. For frames 20-40 everything works fine. Everything also works fine when I move both layers to composition frame 0.
