Mutating CSSStyleDeclaration (via `.setProperty()` for example) does not update injected style

[fsmorygo]

Describe the bug
Mutating CSSStyleDeclaration (via .setProperty() for example) does not update injected style. When I change its value, only ConstructedStyleSheet is changed, but I don't see any changes in DOM

To Reproduce

1. Create and add a Stylesheet with some rules to a Shadow DOM's adoptedStyleSheets
2. Change some property with myRule.style.setPropety('width', '10px)3.
3. Check the DOM and verify no changes have happened.

Expected behavior**
Injected style will update as it would on Chrome with native constructed style sheets support
