Compatibility with Playwright tracefiles?

[unlikelyzero]

Hello!

I'm attempting to parse PerformanceTimelines generated by playwright using the playwright page.trace() functionality.

When I attempt to load a trace file (which is parsed by Chrome DevTools Performance Profiler btw), I get the following:

Failed to find browser main thread in trace, some timeline features may be unavailable
Failed to find browser main thread in trace, some timeline features may be unavailable
Failed to find browser main thread in trace, some timeline features may be unavailable

I understand that this package is not totally maintained, but was wondering if you had some guidance. Thanks!
