Investigate the iframe behavior in rtail's web interface. The issue reports that the page loads but doesn't update. Check if there are cross origin restrictions or sandbox attributes preventing JavaScript from updating the DOM. Look at the client side JavaScript in the repository, possibly in files like client.js or index.html. Also review any server side code that sends updates. Consider if the issue is due to iframe sandboxing or missing 'allow scripts' attribute.
