P: Luminance Range Masking fails on PS Images where Desaturate was used:

Hi, I've noticed this issue with LR Classic 8.1 and Win 10 (1803). I had experienced this problem on a few occasions, but couldn't notice a pattern until now: it only happens with desaturated tiff images (maybe with psd's too). Then I found this report, but I see that, in theory, it was fixed with v7.5.

Anyway, I've captured this small video to show the issue, so that others can check too:

Is it me or is this same problem back? I've also tried disabling GPU, it didn't seem to make a difference.
Thanks.

    I just did a quick test and yes, it looks like it's working as expected now. Thanks!

    Lightroom Classic 8.3 was released today and contained a fix for this issue. Please update to 8.3 and verify that you are no longer seeing the issue. Thank you!

    I can duplicate as well and will log it as a bug. Note: ACR Works as expected.

    I can confirm what you're seeing with LR Classic 8.1 on my Windows 10 1803 system when using RGB TIFF, PSD, or JPEG files that have been completely desaturated (i.e all pixels R=G=B) in PS.

    Actual grayscale TIFFs, RGB TIFFs with only some desaturation, and Leica Monochrome B&W DNGs work correctly with the Luminance Range Mask controls.
