CoreJS minification syntax error

[asadkn]

Using the dev-master release, when minifying the CoreJS that's included with WordPress: https://unpkg.com/core-js-bundle@3.11.0/index.js there appears to be a syntax error around here:
return module.exports}__webpack_require__.m=modules;

The correct syntax would be:
return module.exports};__webpack_require__.m=modules;

EDIT: This doesn't happen in newer versions of webpack where it has changed to function __webpack_require__(moduleId) instead of var __webpack_require__ = function (moduleId) in the preceeding function that causes the issue.

A similar issue is also reported here: #360

Perhaps the minifying of webpack runtime could be skipped altogether considering how messy it is.
