If a property is custom or contains a `var()` reference, it cannot be parsed into a proper StyleValue immediately, so we store it as an UnresolvedStyleValue until the property is compute. Then, at compute time, we resolve them by expanding out any `var()` references, and parsing the result. The implementation here is very naive, and involves copying the UnresolvedStyleValue's tree of StyleComponentValueRules while copying the contents of any `var()`s it finds along the way. This is quite an expensive operation to do every time that the style is computed.
