The commit 306440@main caused a Speedometer3 regression. The commit 307019@main enabled resolving and updating the ::checkmark pseudo element only when cssAppearanceBaseEnabled is on. To enable cssAppearanceBaseEnabled by default, resolving and updating the ::checkmark pseudo element should not rely on the feature flag cssAppearanceBaseEnabled anymore. Instead we can check the style appearance value. If its value is "base", we are allowed to resolve and update the checkmark.
