Icecat and Chromium don't activate the right color scheme of websites

[Luis Felipe]

Hi,

I was wondering if any of you can reproduce the following issue using either 
Icecat or Chromium (ungoogled). I'm using the Guix System ab6e434 and the 
official Guix channel, Icecat 102.8.0esr and Chromium 109.0.5414.119.

STEPS TO REPRODUCE

1. Set your desktop environment or web browser to use a dark theme.
2. Visit https://luis-felipe.gitlab.io/texinfo-css/


EXPECTED RESULT

The visited page is displayed using its dark style.


UNEXPECTED RESULT

The visited page is displayed using its light style.


ADDITIONAL INFORMATION

The light/dark themes provided by the visited page are activated correctly when 
using Epiphany browser in Guix or other web browsers in vaious mobile devices.


QUESTIONS

Do you know of any defaults in Icecat or Chromium that might be preventing the 
expected functionality from working correctly? As far as I understand the 
versions of both Icecat and Chromium in Guix are supposed to support all the 
features required for automatic color scheme activation to work.

Thanks,
