 - Added `Array.prototype.unshift` polyfill with some fixes for modern engines
 - Fixed a bug in the order of getting flags in `RegExp.prototype.flags` in the actual version of V8
 - Fixed property descriptors of some `Math` and `Number` constants
+- Added a workaround of V8 `ArrayBufferDetaching` protector cell invalidation and performance degradation on `structuredClone` feature detection, one more case of [#679](https://github.com/zloirock/core-js/issues/679)
 - Added detection of NodeJS [bug](https://github.com/nodejs/node/issues/41038) in `structuredClone` that can not clone `DOMException` (just in case for future versions that will fix other issues)
 - Compat data:
   - Added NodeJS 18.3 compat data mapping
