Auto Detect Color Scheme

[jhemak]

It does not appear that the option Auto Detect Color Scheme is respected. Whenever I check the box, the color scheme immediately changes to the correct mode (either light or dark, depending on the state of the OS), however it does not automatically change from that point on when the OS mode changes. If I uncheck and recheck the Auto Detect Color Scheme box, the theme again immediately updates to match the OS. So it "works" just not on its own on an ongoing basis. Any ideas?
