Why is the light still bright when IBL / Lights is turned off?

[cx20]

I tried to display AlphaBlendModeTest.gltf in RedCube.js.
However, I did notice that even with both IBL / Lights turned off, the middle of the image was still displayed brightly.

Is this a matter of usage? I had assumed that if I turned off both IBL / Lights, the whole thing would be dark.

Current result:

IBL	Lights	RedCube + AlphaBlendModeTest.gltf result
off	off
off	on
on	off
on	on

@cx20 Actually, it's an incredible interesting bug, this white color is a background of your index.html.
I couldn't reproduce it, because my page has background: #000;

@Reon90 Thanks! As you advised, changing the background color to #000 solved the problem.

@cx20 fixed in 2.5.12
