Steps to reproduce:

1. Open an HDRP project.
2. Import the provided package.
3. Open the scene named {}Chelou{}.
4. Open the VFX asset called {}fire VFX{}.
5. In the Initialize Context, turn the Lifetime On/OFF.

Actual results:  We can see that one quad render changes depending on if the Set Lifetime block is activated or not. All regular Quad, Mesh, and VFX Mesh output have a constant rendering that isn't dependent on the Set Lifetime block.

Expected results: Nothing in the shader is related to the lifetime of particles. Activating the lifetime block shouldn't have any repercussions in this case on the rendering of the particle. Furthermore, there 'should be no discrepancy between what's displayed by the VFX Mesh particle and the VFX Quad particle.
