Really handy!

CSSがオンになっているが実際にはオフで反映されていない時が多くある、この場合は一度オフ・オンすると反映される。　すべてのドメインでオンになるようにしていてもオフになる事も多すぎる There are many times when CSS is turned on but is actually off and not reflected, in which case turning it off and on once will reflect the change.　Too often it is turned off even though it is turned on for all domains.

Need a method to inject styles into shadow-root DOM. Most of news sites' comment box are using shadow root to isolate styles.
