Color wheel, unexpected behaviour on hue change

[aho]

I discovered an unexpected behaviour in the color wheel. When I use the color slider in the hue ring, sometimes the slider in the triangle jumps to the fully saturated color. I expected the slider in the triangle to keep its position within the triangle, just changing the hue, not the brightness or saturation.

After experimenting some more so I could tell you how you could reproduce this, I found that this happens only when the color is fully desaturated, i.e. the color slider in the triangle sits exactly on the line between black and white.

See attached video.

I am using Windows 10 and Affinity Photo 1.8.5.

Confirmed here too, and it does exactly the same in the release and beta versions.
