There seems to be almost 3s of idle time after all the resources have been loaded in before the first render is shown. To isolate the problem, I've created a webpage that has no external packages, and almost no CSS or content.
The page finishes loading all content in 2s but idles until 5s until the first render is displayed. How can I bump up the first render so something is visible on the screen (even if it's not fully loaded) as soon as possible? What's blocking the first render here?
Thanks
