Description
The colors of the symbols in my legend vary randomly each time I make a plot or save it to disk. It shifts between a set of three colors, one of which is completely correct, one of which has a single incorrect color, and one which is all wrong. Run the demo code below several times to see this. I have reproduced this on two separate machines, one of which is running the code in a Docker container.
I have noticed the Please do not ask for support with these customizations active. but since it lists nothing, I'm not sure what to make of that.
