🐛 Bug Report

Assuming colorMode.respectPrefersColorScheme is set to true,

• when colorMode.disableSwitch is false, the color theme changes dynamically when the OS setting is changed, without requiring a full page reload.
• when colorMode.disableSwitch is true, this behavior doesn't work. Instead, the user has to reload the page for the correct color theme to kick in.
