## Testing Considerations

The `ConfirmationModal` component uses the native `HTMLDialogElement` API for better accessibility and browser-native behavior. However, `JSDOM` (used by `Jest` and other test runners) does not fully support this API. You'll need to mock the `show`, `showModal`, and `close` methods in your test setup:

```tsx
beforeAll(() => {
  HTMLDialogElement.prototype.show = jest.fn(function mock(
    this: HTMLDialogElement,
  ) {
    this.open = true;
  });

  HTMLDialogElement.prototype.showModal = jest.fn(function mock(
    this: HTMLDialogElement,
  ) {
    this.open = true;
  });

  HTMLDialogElement.prototype.close = jest.fn(function mock(
    this: HTMLDialogElement,
  ) {
    this.open = false;
  });
});
```

This mock can be placed in a `beforeAll` block in your test file, or in a global test setup file.
