Toggling CSSStyleSheet::disabled previously cleared the cached media match bits and reloaded fonts, but never informed the owning documents or shadow roots that style resolution was now stale. Worse, the IDL binding for the disabled attribute dispatches through a non-virtual setter on StyleSheet, so any override on CSSStyleSheet was bypassed entirely. Make set_disabled() virtual so the CSSStyleSheet override actually runs, snapshot the pre-mutation shadow-root stylesheet effects before flipping the flag, and hand them to invalidate_owners() so a disable that strips the last host-reaching rule still tears down host-side style correctly.
