AlphaOverLifetimeLinearGradient only works on UnlitMaterial

[zahndy]

Describe the bug?

AlphaOverLifetimeLinearGradient only works on UnlitMaterial, if any other material is used no fade-in/out seems to happen even though the material is set to Alpha.

To Reproduce

spawn a ExperimentalParticleSystem.
add a AlphaOverLifetimeLinearGradient to ParticleStyle.
set it to Alpha Fade In & Fade Out
create a PBS_Metalic/PBS_Specular/UnlitDistanceLerpMaterial
copy over the Unlit's texture to the Albedo and set the material's Blendmode to Alpha
observe AlphaOverLifetimeLinearGradient no longer working

Expected behavior

To have AlphaOverLifetimeLinearGradient apply to any material that has Alpha blend.

AlphaOverLifetimeLinearGradient or any particle modules that affect color use any materials that support vertex colors. This includes PBS vertex color metallic and specular.
