_official-realtime-app example is buggy

[rgov]

When I load the _official-realtime-app example on CodeSandbox, I notice that:

• When viewing a single issue, even though it says, "That title is content editable and will save on blur," when I edit the title it just reverts back after a moment. (Edit: Also reproduces on my local machine.)

• The back button in the integrated browser doesn't work. (Edit: Doesn't reproduce on my local machine, but pressing the back button takes almost a full second to go back to which is not great for a simple example project in a framework that purports to be very fast.)

Also _official-tutorial results in a "502 Bad Gateway" on CodeSandbox.

Edit: Locally, rpm run dev just prints 💿 Built in 329ms and then does nothing further.

I'm not sure if any of the examples work, I'm 0 for 3...

If you npm run build and then npm start, it works 🤷‍♂️

npm run build and npm start does seem to allow the example to function properly.
Why is this example not working correctly when running npm run dev?

I see the same issue on the example based on this example that was shown at RemixConf 2023:
