Able to reproduce this issue on reported version 65.0.3325.181 and on latest canary 67.0.3381.0 using Mac 10.13.3, Windows 10 and Ubuntu 14.04. No entry with name test is seen in Performance tab and sometimes error is seen in console. NOTE: In Firefox able to see test entry in Performance tab. This issue is seen from M-60. Hence considering this issue as Non-Regression and marking as Untriaged. Thanks!

CPU profiles added to the JavaScript profiler panel. You can open it by clicking three dots menu (in the top right corner) ⋮-> More tools -> JavaScript Profiler. |
