Is this a bug in the spec? https://github.com/tc39/test262/blob/master/test/built-ins/RegExp/Symbol.species/symbol-species.js <https://github.com/tc39/test262/blob/master/test/built-ins/RegExp/Symbol.species/symbol-species.js> tests that the RegExp[Symbol.species] property is configurable. Additionally, it appears to break at least one major webpage if RegExp[Symbol.species] is not configurable.
