I agree. It does preserve the transforms, which I think makes sense since then one can refine the flame graph. For instance, dropping samples from `__poll`.

Seems like it doesn't store the markers in the payload, just the timestamps. https://searchfox.org/mozilla-central/source/dom/performance/Performance.cpp#366 ```C++ #ifdef MOZ_GECKO_PROFILER if (profiler_is_active()) { TimeStamp startTimeStamp = CreationTimeStamp() + TimeDuration::FromMilliseconds(startTime); TimeStamp endTimeStamp = CreationTimeStamp()...
