Adds a test that shows using anywhere outside of the root node will not fire strict effects.

This works:

root.render(
  <StrictMode>
    <App>
      <Children />
    </App>
  </StrictMode>
);

This does not fire strict effects on mount:

root.render(
  <App>
    <StrictMode>
      <Children />
    </StrictMode>
  </App>
);
