Light/dark theme disconnected from light/dark scheme

Expected behavior

After reading this, as well as squidfunk/mkdocs-material#1266, my understanding is:

1. Toggling the theme using the toggle switch will switch the preferred color scheme; and
2. Switching the preferred color scheme will toggle the theme.

However, they are disconnected as far as I can tell.

Observed behavior

1. Toggling the theme using the switch in the header of this page will update the theme, but not the scheme.
2. Toggling the preferred color scheme (e.g., on MacOS, switching from Light to Dark in System Preferences » General » Appearance) will update the scheme, but not the theme.

Detail

I have created an example that illustrates this. (Source can be found at posita/mkdocs-dark-bug.)

Test matrix:

Theme 👉 Scheme 👇	Light	Dark
Light
Dark

Tested with:

package	version
mkdocs	1.1.2
mkdocs-material	7.1.6
mkdocs-material-extensions	1.0.1

I’m happy to announce that automatic dark/light mode was finally implemented and just released as part of 8.3.4+insiders-4.18.0. I invite you to test-drive it on our documentation. Here’s a short video showing how it works:
