Photoshop 21.2: Problem with the Curves and Levels histograms and clipping masks

This is an example on how the problem occurs (Ps 21.2):


1.- select one zone of your image
2.- duplicate it (by Command/Ctrl+j for example)
3.- add a adjustment layer (curves or levels)
4.- you can see an histogram (in the curve or levels properties) corresponding the whole image
5.- now convert this layer (the curve or levels) to clipping mask


And here is where the "bug" appear:

The histogram remains the same (corresponding the whole image). Normally this histogram must to change to correspond to only the info in the layer just below.


NOTE 1: this problem no exists in v21.1.3

NOTE 2: by the way, the "normal behavior" in the histogram is shown if we turn off the original image (ie if we leave active the layer with the duplicate area and clipping mask).


I would appreciate any ideas or workaround

If you go to Preferences > Performance... and uncheck "Legacy Compositing" does it work correctly?

Are you using the correct option in the Histogram Expanded Options dropdown menu? Entire Image or Selected Layer?
