Is there an existing issue for this?

• I have searched the existing issues
• I have read the guide to filing a bug

Steps to reproduce

1. Launch any flutter web app using flutter run -d web-server
2. Proceed to provided url
3. Notice that flutter-loader element (which is the animating blue line at the top) remains forever in DOM

Expected results

Animating loader element should be removed instead of hidden by the app rendering on top.

Actual results

Animating loader element continues to animate indefinitely causing layout shifts and making it more difficult to test performance.
