What is expected?

Calling resolve from a plugin (sonda in this case) should not influence the functionality of the bundled application.

What is actually happening?

Adding a plugin such as

{
      name: 'sonda-like-resolver',
      async resolveId(source, importer, options) {
        if (!importer) {
          return;
        }

        const resolved = await this.resolve(source, importer, {
          ...options,
          skipSelf: true,
        });

        return resolved;
      },
    }

breaks the application at runtime.

It fails with n is not a function
