Version

1.55.0

Steps to reproduce

1. Given you start a test in UI mode (or load trace in trace viewer)
2. And you go to the network tabs
3. And you open the body subtab for some response (this loads fine)
4. And you now switch browser tab
5. And wait some minutes
6. And you go back to the Playwright browser tab
7. Then opening any response body shows <Empty>

Expected behavior

While expected to see the response body.

Actual behavior

Seeing <Empty> (which is really annoying, especially if the test has a large duration, which now has to be started again, just to see some network response)

And console (network) errors for the sha1 network requests:
Failed to load resource: the server responded with a status of 404 ()

Additional context

No response
