P: TAT in Color Mixer adjusts bands 2-colors off from hovered-over color when image is HDR

[umlautnord]

Issue: The Color Mixer Target Adjustment Tool does not choose the correct color(s) for H/S/L adjustment when HDR editing is enabled. 

It should choose, and then adjust, the color/two-color mix that is clicked on. However, that selection seems to be skewed in HDR-enabled images. For example, blue sky will register only as magenta if using the target tool. This problem occurs in both non-HDR and HDR areas of an HDR-enabled image.

If HDR editing is then disabled for the same image, the target adjustment tool will identify and adjust the appropriate colors when going to the exact same spots.

Video attached of incorrect behavior in HDR editing mode. The image used in the video is a JPG, but I have confirmed this behavior also occurs on a DNG.

I can replicate the behavior in Lightroom Classic but not in Camera Raw. I have logged a bug with the Classic team.
