Repository: flutter
Issue: [Web] canvas.js seems to fail to load randomly 
Labels: platform-web,a: production,team-web

### Steps to reproduce

Unfortunately I don't have a reproduction scenario, since this is a feedback I got from some of the users of my Flutter Web project in production.
It is not something I have seen in Debug either.

### Expected results

The web app should load consistantly

### Actual results

In some random cases, the users with the issue can see this error message in the chrome console:

`Cannot use 'import.meta' outside a module` coming from the `canvaskit.js` file


### Code sample

<details open><summary>Code sample</summary>

This is what my startup code in JS looks like, that is referenced in the screenshot as the `flutter_bootstrap.js` file:

```js
function launchFlutter(){
  var version =  {{flutter_service_worker_version}};

  _flutter.loader.load({
    config: {
      // https://github.com/flutter/flutter/issues/148713#issuecomment-2129976660
      canvasKitBaseUrl: "/canvaskit/",
    },
    serviceWorkerSettings: {
      serviceWorkerVersion: version,
    },
    onEntrypointLoaded: async function(engineInitializer) {
      const appRunner = await engineInitializer.initializeEngine({
        useColorEmoji: true
      });
      loading.remove();
      await appRunner.runApp();
    }
  });
}
```
