When running the Python fetch tests: pytest --browser chromium tests/async/test_fetch_browser_context.py tests/async/test_fetch_global.py

Leaks here:

        socket.on('lookup', () => {
          dnsLookupAt = (0, _utils.monotonicTime)();
        });

I've used microsoft/playwright-python#2584 to test 1.49.0-alpha-2024-10-07 vs 1.49.0-alpha-2024-10-08, which contains #32956. The test confirmed that it fixes the MaxListenersExceededWarning.
