The revision numbers stated in the flakiness dashboard seem to be wrong sometimes.

e.g. https://test-results.appspot.com/dashboards/flakiness_dashboard.html#testType=ipc_tests%20(with%20patch)&showAllRuns=true&tests=IPCChannelMojoTest.VerifyGlobalPid

Clicking the coloured boxes shows revision ids around r519xxx, but the actual builds are for revisions around r577xxx.
