Details
Currently we are using the eventDelay data for creating jank markers in the frontend. But we also have "Long Task" markers that might indicate jank for a while now. Looking at the profiles, we've seen that they mostly correlate to each other. We should consider replacing them with Long Task markers.
But we've also seen some cases where they don't always match. So we should also look at those areas and try to understand why (and fix if there are any bugs).
