Bug: Code generation fails when a component imports an asset (eg. svg file) or an ESM module

[cassus]

Given

import React from "react"
import SvgAsset from "./asset.svg"


export function ComponentWithAsset() {
    return <div>
        <img src={SvgAsset} />
    </div>
}

import { ComponentWithAsset } from '../components/ComponentWithAsset';

const { Given, When, Then } = createBdd(test);

Given('Mounted component with asset imported', async ({mount}) => {
  await mount(<ComponentWithAsset />);
});

When
I generate the tests

Then

Command failed: node ../node_modules/playwright-bdd/dist/cli && npx playwright test
/Users/cassus/Dev/playwright-bdd/test/component-tests/components/asset.svg:1

But I expect
Code generation to work as it works when there is no asset import in the component test

Isolated demo
I extended test/component-tests with this case, see my branch at
https://github.com/cassus/playwright-bdd/tree/cassus/comp-test-asset

Environment

Playwright-bdd environment info:
platform: darwin
node: v20.10.0
playwright-bdd: v5.6.0
@playwright/test: v1.36.2
@cucumber/cucumber: v9.6.0

Additional thoughts
This issue reminds me of the errors I get when I accidentally import a component that uses assets in my e2e playwright tests. It seems like playwright-ct test runner parses the code in a different way that avoids errors like this.

Possibly related error during code generation when importing an ESM module from a component. When running playwright component tests this ESM module imports and works fine.

Error: Cucumber expected a CommonJS module at '/Users/cassus/Dev/org-mat-viz/src/features/participate/e2e/ConditionalQuestions.steps.comp.tsx' but found an ES module.
      Either change the file to CommonJS syntax or use the --import directive instead of --require.

Instead change the require of index.js in /Users/cassus/Dev/org-mat-viz/src/lib/ReactMarkdown/InlineMarkdown.tsx to a dynamic import() which is available in all CommonJS modules.
