Background turns black when zooming out
I would like to keep the background a constant color when zooming in/out.
I discovered various issues about the background color. These suggested setting background_image property. This works, but the image still becomes lighter/darker when zoomed.
Another issue suggested setting the background color of the surrounding div. This only seemed to have a mild effect when zooming in. But not at all when zooming out. Here's an example with the surrounding div background set to red:

I personally also discovered zoom_modify_alpha property. Setting this to false disables the gradual darkening/lightening. But at one point the background simply flips to black. Here's a demonstration of the following settings:
canvas.background_image = "/grid.png"; // non-transparent image
canvas.zoom_modify_alpha = false;

More likely though there's something messed up in the surrounding environment where I'm using litegraph... this project I'm working with is such a mess :(
