Contributor guide
Research direction
Start by opening the two linked Firefox Profiler examples: the example profile and the profile of the jank. Investigate the marker chart rendering path responsible for the reported 500ms delay. Done means the marker chart no longer causes the reported jank when shown for this thread.
