**Investigation**
~~We use `nonStallingEvaluateInExistingContext` as of today, which does
`eval()` inside (from our utilityScript) which breaks for some sites. It
causes a hang, since the returned `Promise` of `eval()` hangs. We don't
know as of today why this happens. Without wrapping it ini `eval()` it
does not hang.~~
~~Workaround: Do a plain Runtime.evaluate instead.~~
workaround: Only wait on main frame.

When a signal arrives late enough, after the last action was committed
in 5 seconds, we should still account for it. This includes downloads,
popups and dialogs, but not navigations.
Exposed by a flaky test "should record open in a new tab with url".
This includes two major changes:
- reuse `SerializedFS` for live test runner tracing;
- merge scheduled `appendFile` operations into a single `fs` call.
In some cases, this improves performance of UI mode by 61% and
performance of `trace: on` mode by 38%. Note that performance
improvement on the average test will not be as noticeable.

Chromium's `DevTools listening on` message sometimes arrives before
Playwright is finished connecting to Node. Without this patch, it would
miss the message and fail to connect.
This is a follow up #29564
I did a deep dive on a redirect issue I observed in my infrastructure
and originally attributed to some configuration mistakes on my part.
I have code hosted on `example.com/code` and use subdomain proxying.
This leads to the uimode being exposed on
`example.com/code/proxy/{{port}}`.
Clicking on the open uimode link shown by vscode redirected with a 302
to `example.com/proxy/{{port}}`
The absolute redirect url overruled the relative path handling reverse
proxies rely on.
This PR turns the absolute into a relative url to avoid this issue.
Matching bu `apiName@wallTime` fails when two actions start at the same
time, e.g. two parallel api requests. Moreover, it results in trace
actions that have parent set to themselves, which in turn causes
infinite loop in the trace viewer. To avoid this problems we write
stepId explicitly to the library trace and use those step ids to find
corresponding test runner steps.
The stepId is passed via zone in case of expect, because the protocol
step is quite deep in the call chain after or explicitly in case of API
call steps created by the test runner instrumentation.
Similarly to page.close, we pass test-runner specific reason to
facilitate better error messages.
```
1) a.test.ts:10:11 › test
Error: apiRequestContext.fetch: Fixture { request } from beforeAll cannot be reused in a test.
- Recommended fix: use a separate { request } in the test.
- Alternatively, manually create APIRequestContext in beforeAll and dispose it in afterAll.
See https://playwright.dev/docs/api-testing#sending-api-requests-from-ui-tests for more details.
