Translucent deferred decal materials look different when setting specular attribute directly or via constant node

Translucent deferred decal materials look different when setting their specular material attribute directly on the material node versus setting it via a constant node

• Create a new material with Domain set as DeferredDecal, Blend mode as Translucent
• Set the Metallic, Specular and Roughness attributes to 0.0, 1.0, 0.0 respectively directly on the main material node
• Add a texture as base color
• Duplicate this material and set the Specular attribute to 1.0 via a constant value node
• Create two planes and apply each material to a plane
• Observe differences in visual output
