To ensure that window.top is restored even if an assertion within the test fails, it's a best practice to place the cleanup logic in a finally block. This guarantees that the original state is restored, improving test isolation and preventing potential side effects on other tests.

    try {
      // Try to define a property that throws when accessed
      // Note: In some jsdom environments window.top might be non-configurable.
      // If this fails, we might need a different strategy, but this is the standard way to mock cross-origin.
      try {
        Object.defineProperty(window, 'top', {
          get: () => {
            throw new DOMException('Permission denied to access property "removeEventListener" on cross-origin object', 'SecurityError');
          },
          configurable: true,
        });
      } catch (e) {
        // Fallback: If we can't mock window.top, we skip this specific test implementation details
        // and rely on the fact that we modified the source code.
        // But let's try to verify if we can mock it.
