Fix dark mode detection for system theme for highlight unfolded comments

Open cherryblossom000 opened this issue 4 years ago • 2 comments

When the dark mode is set to ‘System setting’, the theme-dark class isn't present and instead theme-system is on the body element.

Screenshot of HTML source of StackOverflow page, showing that the theme-dark class is not present on the body element. The body instead has a theme-system class which is referred to in the styles tab of the Chrome DevTools as @media (prefers-color-scheme: dark) body.theme-system.

This PR uses window.matchMedia if the body class is theme-system to detect if the prefers-color-scheme is dark.

Fixes #22

A workaround for now is to edit the userscript installed to include this patch (so you don't have to wait for this PR to be merged to use the fix).
