CSSStyleSheetHeaderIsMutable Property

Whether this stylesheet is mutable. Inline stylesheets become mutable after they have been modified via CSSOM API. `<link>` element's stylesheets become mutable only if DevTools modifies them. Constructed stylesheets (new CSSStyleSheet()) are mutable immediately after creation.
