Attempting to run a benchmark locally and view output results.html is throwing a JS error after loading ~80% of the data. This has been happening at least the past two days.

Seems potentially P1 since eng can't easily investigate broken benchmarks but feel free to lower priority if I am off base.

To repro:

% tools/perf/run_benchmark -v --pageset-repeat=1 --browser=release rasterize_and_record_micro.top_25

and try opening the results.html via link printed to console. I see for example:

Loading Histogram 5100 of 5152

and then JS error and hang. It does not always hang at the same displayed histogram progress point, for example, reloading a few times also gives me:

Loading Histogram 4600 of 5152

Sample error in console:

Uncaught (in promise) Error: Unrecognized diagnostic type: TelemetryInfo
