Fixes#24144.
Previously, we only matched by url, which confuses GET and HEAD requests
where the latter is usually zero-sized.
Also make sure that resources are sorted by their monotonicTime, since
that's not always the case in the trace file, where they are sorted by
the "response body retrieved" time.
- feat(tracing): mark API requests with "API" label
- feat(tracing): do not attribute any resources to `route.` API calls;
otherwise, network traffic might get inside the `route.` actions.
- fix(tracing): map actionIds from primary contexts to actionIds from
non-primary contexts
- fix(tracing): show leading `/` in URL path in network panel
This is a result of a pair-programming session with @pavelfeldman
- Do not resolve raw headers upon `loadingFinished`, since they may still come later in
`responseReceivedExtraInfo`.
- Introduce separate promises for `encodedBodySize`, `transferSize` and `responseHeadersSize`.
- Make sure we resolve each of them either with data available
from the browser, or a fallback calculation.
- Set raw response headers for redirects on WebKit.
- Do not stall on cached responses in Chromium, they have erroneously set `hasExtraInfo` flag.
- Use `transferSize` that is available in Firefox protocol.
Currently, `loadstate` and `load` are two separate events in the protocol,
and are fired in this order. As a result, `waitForLoadState()` sometimes
resolves before the `'load'` event is fired, which is unexpected.
Also fixes a flaky test that assumed `load` event comes after `domcontentloaded`
for the empty page, which is not always a case in Chromium.
