Describe the bug

Steps to reproduce the behavior:

1. Code for rendering a simple banner (without useEffect or useState) on the thank you page

import {
  reactExtension,
  View,
  Banner
} from '@shopify/ui-extensions-react/checkout';
export default reactExtension(
  'purchase.thank-you.block.render',
  () => <Extension />,
);
function Extension() {
  console.log(`render extension at ${Date.now()}`);
  return <View>
    <Banner
      status="critical"
      title="My extension"
    />
  </View>;
}

2. Position and save the extension on the thank you page in the editor. UI has only one banner as expected, but we can see console.log has been executed twice.
3. The same thing happens on the actual Thank you page.

Expected behavior

console.log should only execute once.
