+ * TODO: The `--require` flag is processed in `loadPreloadModules` (process/pre_execution.js) BEFORE

+ * run) but then the root test-case is created, causing the "subsequent" hooks to get lost. This
+ * behaviour (CJS route only) is different from the ESM route, where test runner explicitly handles
+ * `--import` in `root.runInAsyncScope` (test_runner/runner.js).
