Please, upgrade your dependencies to the actual version of core-js. Some versions have web compatibility issues. Because of the V8 engine whims, feature detection in old core-js versions could cause a slowdown up to 100x even if nothing is polyfilled. Npm WARN deprecated is no longer maintained and not recommended for usage due to the number of issues.
