### Link to the code that reproduces this issue https://github.com/rishabh3112/next-15-swc-external-helpers-bug ### To Reproduce 1. Clone reproduction repo 2. `npm install` 3. `npm run dev` ### Current vs. Expected behavior It should work as it was working in next 14. #### Current: After webpack parsing with external helper (Next 15): ``` __webpack_require__.r(__webpack_exports__); /* harmony import */ var _swc_helpers_type_of__WEBPACK_IMPORTED_MODULE_0__ = __webpack_require__(/*! @swc/helpers/_/_type_of */ "./node_modules/@swc/helpers/esm/_type_of.js"); (function(root, factory) { if (typeof define === "function" && __webpack_require__.amdO) { define([ "exports" ], function(exports1) { root.Backbone = factory(root, exports1); }); } else if (typeof exports !== "undefined") { factory(root, exports); } else { root.Backbone = factory(root, {}); } })(window, function(root, Backbone) { // Removed actual backbone code for minimal reproduction Backbone.Modal = function() { var something = root.something; // So that _type_of swc helper import gets added to the code if ((typeof something === "undefined" ? "undefined" : (0,_swc_helpers_type_of__WEBPACK_IMPORTED_MODULE_0__._)(something)) === "object") { return "object"; } return "don't know"; }; return Backbone; }); ``` SWC playground link: [link](https://play.swc.rs/?version=1.9.2&code=H4sIAAAAAAAAA31RMW7DMBDb8wrWQ%2BoARfKAwEv3LulYFIEjnRM1ts6Q5bpB4L9XsqRAS7vYwJFH8qiyGbWwijVKw2xf0NTCsrltcF8BqkFpbz1xA0mN0oSqqlCknQLrdQS2dSfDDuKk%2FCjop2djh%2BLTyT5s4jCRAe%2B7fa3F9cTeICWIeRJ9v7Dn5T%2BD2oHydJGFJx9v1CGBLJLJ35JRKtD%2BT3KP5qt5U05KS57yswInLQfj3Q4H6vibJJzSWLc4JXHBktCwQae06hxiqDcsx0XNrSah7RtLh1aZUzpKsB4sBu7IXpQ%2BO86S%2FzEIjbkM7wx7qS2Ovqyja2uYBC7U9mSgOt8FzuTKq6V0Sa1nh4CLQNZy5uV75tMXCVtkL0l2NPoBxCdb5ZBk%2FWxx1Twt8Ow%2FEUsn713B%2B1%2BA%2B%2BJUmAIAAA%3D%3D&config=H4sIAAAAAAAAA22PSw7CMAxE95wi8potL…
