yes it does, but my pull request got a warning instead…

The issue is that wordpress removes empty p tags.
You can replace the following line in contact-form.php for now:
- '<p role="status" aria-live="polite" aria-atomic="true">%s</p>',
+ '<span role="status" aria-live="polite" aria-atomic="true">%s</span>'
