This change regresses current behavior: there is no way to override color scheme preference in the early stage of page load as there is inherent delay between navigation commit and when the front-end can set the override back. Basically this code will always give wrong result if run early during page load:

// Send Page.setForcedAppearance with "appearance":"Light"
// navigate to a page with the following code in its inline script:
console.log(matchMedia('(prefers-color-scheme: light)').matches);
