To be more precise, I need parity with how browsers render HTML5 canvas - and they do not seem to take that last correction step you listed.
If I mix a 255 color with a 0 color on my browser, the result will be a 128 color - not a 188 color.

Is there any option on GIMP 2.10 to mimic this behavior, or is downgrading to 2.8 a better out for me?  

You can try painting in a transparent overlay, using perceptual mode. Might work for you.

Thanks!

Perceptual mode on the layer properties does work for what I want!
