Unexpected behavior after call of Renderer.material

Any access to `gameObject.GetComponent<Renderer>().material` will make the VisualEffect oddly behaves.

Step to repro:

• Import Repro_Material.unitypackage (the scene uses HDRP but the repro is compatible with URP)
• Enter in PlayMode
• Observe the color of the VFX evolving
• Click on the boolean "repro_issue" in inspector of the custom monobehavior
• Observe the color stopping to evolve

Expected:

• The color continue to evolve
