Description
All textures, when they haven't loaded yet, default to grey. For the emmissive channel of PBR, a grey texture means the whole object glows quite brightly. Normally, emmisive textures are mostly black. So, when a pbr emmissive texture is present but not downloaded, the viewer should replace it with a solid black texture

Research direction
Start by tracing the viewer's PBR emissive texture loading and fallback path, focusing on what happens while an emissive map is unavailable. Verify the result with an object using an unloaded emissive texture: the temporary texture should appear black rather than grey, without changing other texture channels.
