(macOS) Photoshop 27.11 Save for Web "Embed Color Profile" checkbox has no effect with Modern User Interface

In Photoshop 27.11 on macOS (I’m using latest Golden Gate), Save for Web fails to embed color profiles in saved images if the Modern User Interface is being used.  The “Embed Color Profile” checkbox is essentially ignored, and the checkbox and other controls behave strangely, such as the checkbox being instantly unchecked by making any other changes to the settings in Save for Web (such as changing the Quality).

When the Modern User Interface is turned off, the “Embed Color Profile” checkbox in Save for Web then works as expected and the saved file contains the color profile as expected.

Steps to reproduce:

1. The Modern User Interface must already be active (ensure that Photoshop Settings - Technology Previews - “Enable Modern User Interface” is checked, and restart Photoshop for the change to take effect)

2. Open an image file that has a color profile, e.g. Adobe RGB, sRGB, P3, etc

2. Open Save for Web from File - Export - Save for Web... and ensure the image type is JPEG and that the “Embed Color Profile” checkbox is checked

3. Adjust the Quality and note that the “Embed Color Profile” checkbox immediately unchecks again

4. Re-check the “Embed Color Profile” checkbox and then click “Save...” to save the JPEG file

5. Open the newly saved image in Photoshop or another image editor and note that the file has no color profile embedded

If you then turn off the Modern User Interface by unchecking the “Enable Modern User Interface” checkbox in Photoshop Settings - Technology Previews and restart Photoshop for the change to take effect, then try the steps again, the “Embed Color Profile” checkbox behaves normally and the saved file will correctly contain the color profile.

It appears the bug might be specific to Photoshop on macOS.
