As I understand it, this looks like it's mostly testing loading. When I reproduce manually, steps 4 and 5 feel very fast (5 is pretty much instantaneous, at least on my browser). Step 3 takes quite some time. If I do not wait for the load before pressing End, it takes quite a while. Which makes sense; it needs to load before it can go to the end.

So this looks like a page load problem, which is consistent with most of the Google Docs cases I have looked at.

Unfortunately, a profiler bug prevent me from getting the category percentages for the content process main thread right now.

WONTFIX for now to limit perf benchmark bugs to high impact. Please re-opened when new input latency metrics landed and confirm this issue.
