…pport top level await Top level await expects that all module script evaluation returns a Promise. As such, update ModuleWrap::SyntheticModuleEvaluationStepsCallback to return a resolved Promise now that V8 has enabled top-level await by default. Unfortunately I don't have a spec reference that I can point to here because the Built-in modules proposal isn't yet updated for top level await. The corresponding change for Blink is https://chromium-review.googlesource.com/c/chromium/src/+/2568823. This will allow a workaround for Node in this V8 bugfix to be removed: https://chromium-review.googlesource.com/c/v8/v8/+/2673794. Fixes: nodejs#37299

Top-level await expects that all module script evaluation returns a Promise. As such, ModuleWrap::SyntheticModuleEvaluationStepsCallback should be updated to return a resolved Promise now that V8 has enabled top-level await by default.
Unfortunately I don't have a spec reference that I can point to here because the Stage 1 Built-in modules proposal isn't yet updated for top-level await.
For reference, the corresponding change for Blink is https://chromium-review.googlesource.com/c/chromium/src/+/2568823.
I discovered this issue when working on this V8 bugfix: https://chromium-review.googlesource.com/c/v8/v8/+/2673794. My first attempt at a fix failed the Node integration tests because it assumed that the Synthetic Module callback steps return a Promise. For now, I'm adding a workaround for this in V8 but if Node can make this update then we'd like to eventually remove that workaround.
