Some gradient interpolations are quite broken

[kazerniel]

Description

Certain colour combinations make the gradient go wild. I don't even mean that gradients of end stops of <9 lightness difference fail to generate altogether, but this:

Steps to reproduce

1. Go to http://leonardocolor.io/
2. Generate a sequential gradient between #054cbe and #8a7401 in the OKLCH colour space.

Expected behavior

Smooth gradient.

Screenshots

Some of the other colour interpolations bug out too.

HSL and HSV's circle analysis counts as abstract art :)
