The "use archive" checkbox in the bisection dialog on the performance dashboard is ignored. More specifically, even if you uncheck it, the bot will re-use the build from the archive.

This is a bisect which I started with the "use archive" checkbox unchecked: https://chromeperf.appspot.com/buildbucket_job_status/9003899331866169952
Nevertheless, the bisect is clearly reusing the build from the archive: https://build.chromium.org/p/tryserver.chromium.perf/builders/mac_retina_perf_bisect/builds/1589/steps/Gathering%20reference%20values.extract%20build/logs/stdio
