There’s a minor (albeit still confusing) bug in the web UI: If you have a build with multiple jobs and you restart the first job while others are still running, the “running for” time at the top gets reset and will match the build you just restarted. I’d expect the time at the top to continue going instead of getting reset.
Note how at the top it says “Running for 6 sec” which matches the first build I restarted. This doesn’t make sense because the other builds took over 2 minutes each.
