This Bug seems to be around for a few versions now. Color picker behavior in HSL curves is very erratic and inconsistent. Makes teaching or using it - ****.
I've experienced it in varying degrees of dis-functioning in 2019 and 2020. on Mac.
These tools (just introduced in Fall 2019) are so essential in so many color workflows.
Please look into this. It seems minor enough to be easily fixed.
