Additional context

I'm unable to upgrade the Angular and web/lit component testing libraries from version v1.41.0 to v1.41.1 because the transform process was improved recently. The issue lies in the components not being transformed into refs. This occurs because Angular/Lit components are used as .ts files, while the transformation process in playwright-ct-core only handles non-JavaScript imports, as indicated here: https://github.com/microsoft/playwright/blob/main/packages/playwright-ct-core/src/tsxTransform.ts#L78

Is it an option to verify if the import is used within the mount() instead of verifying the file extension?
