[wuifdesign]

• @testing-library/preact version: 3.2.3
• preact version: 10.13.2
• node version: 18.14.0
• npm version: 9.3.1

What happened:

Starting with v3.1.0 i have problems running my tests with jest.

When running jest i get following error:

.../node_modules/@testing-library/preact/dist/esm/index.mjs:1
    ({"Object.<anonymous>":function(module,exports,require,__dirname,__filename,jest){import { cleanup } from "./pure.mjs";
                                                                                      ^^^^^^

    SyntaxError: Cannot use import statement outside a module

const config = {
  testEnvironment: 'jsdom',
  transform: {
    '\\.[jt]sx?$': ['@swc/jest']
  }
}

We’re getting this same error while running our tests. Tests pass when using version 2.0.1 of this package, but fail in 3.0.0.
