Duplicate IssueBeginFrame When Computing Pipeline Metrics

Project Member Reported by chiniforooshan@chromium.org, Nov 5 
When I run rendering.desktop benchmark, on ToT, I get the following error:

page_test_results.Fail:540  Failure recorded: Error: Unexpected duplicate step: IssueBeginFrame

The commend that I run is:
tools/perf/run_benchmark run rendering.desktop --browser=system --output-dir=<OUTDIR> --pageset-repeat=1 --story-filter=amazon_2018

A trace from a run is attached.

Hm, interesting. I could repro this from the 'system' browser, which for me is 70.0.3538.77. I couldn't repro on tot, or on unstable (which for me is 72.0.3602.2). Perhaps there was a trace-event related bug in the earlier versions?

I am going to bump the priority to 3 since this is not repro-ing on unstable or tot.

It doesn't look like this is happening? I suspect some change already resolved this issue.
