Previously, calling `setProperty` or `removeProperty` from JS on a CSSStyleDeclaration returned from `getComputedStyle()` would return null. We now return a NoModificationAllowedError instead, which aligns our implementation with the specification. (cherry picked from commit ea68bdef26260762dec02413cce0d79caef6f4a4)
