[Bug]: compatibility plugin not works well

[bvanjoi]

System Info

@rspack/core: "0.7.4"

Details

// a.js
module.exports = "a"
// index.js
function f(__webpack_require__) {
  require('./a.js');
  __webpack_require__ + 1
}

expect after npx rspack build:

function f(__nested_webpack_require_11__) {
  __webpack_require__("./src/a.js");
  __nested_webpack_require_11__ + 1
}

actually:

function f(__webpack_require__) {
  __webpack_require__("./src/a.js");
  __webpack_require__ + 1
}
