SUMMARY
In latest Krita nightly builds, the HSV/HSL Adjustment filter is very hard to use and is often dysfunctional.

STEPS TO REPRODUCE
1. Paint an orange line.
2. Add a Filter Mask for HSV/HSL Adjustment filter.
3. Notice that all the sliders are initially black.
4. Enable Colorize.
5. Setting Hue to the far left of the slider will break the filter completely, producing no effect.
6. If Hue is set to the right of the slider, setting Saturation to the far left of the slider will break the Value slider.

Occurs in git 855096 (3/26/23), git daf98f (2/28/23), but NOT in 743b90 (2/2/2023).
