Syntax lowering bug

[elsassph]

Describe the bug

Having a bug when using syntax lowering with the stylis dependency - some imports aren't transformed correctly.

Input code

// stylis/Parser.js
import { from, /*...*/ } from './Utility.js'
import { char, /*...*/ } from './Tokenizer.js'

/*...*/
return node(value, root, parent, COMMENT, from(char()), /*...*/
/*...*/

Config

See rspack.config.mjs

function getSwcOptions(es5) {
  return es5 === "1"
    ? {
        isModule: "unknown",
        jsc: {
          externalHelpers: true,
        },
        env: {
          mode: "usage",
          coreJs: "3.40.0",
          target: "es2015",
        },
      }
    : undefined;
}

Expected behavior

Should compile from(char()) into

(0,_Utility_js__WEBPACK_IMPORTED_MODULE_1__.from)((0,_Tokenizer_js__WEBPACK_IMPORTED_MODULE_0__.char)())

Actual behavior

Incorrectly compile from(char()) into

(0,_Utility_js__WEBPACK_IMPORTED_MODULE_1__.from)(char())

e.g. the char() call isn't transformed - all other imports are correctly transformed.

Version

1.2.2

Additional context

Invoke test project as pnpm run dev:rspack:es5 to enable syntax lowering (crash in browser)
and compare with pnpm run dev:rspack to bundle without lowering (OK in browser)

Sorry maybe I should have raised that in RSpack project.
