Alpha blending issue between identical colors

This is especially noticeable with darker colors, but is still an issue with lighter colors, just imperceptible until you try to fill what appears to be a single color.
To reproduce:
1) Draw a blob of a color on a layer (ff0a0f14 works well as it is darker)
2) Add a layer above it and draw some more of this color on top of itself
3) Slide the alpha of the top layer up and down
You will see that the color where the two identical colors overlap changes to various slightly darker tones, whereas we should expect a color blended with itself to result in an identical color.
This is also an issue for brushes with alpha.
