The network events all still look accurate so it looks like a change in how the inspector interacts with the js profiler (or a move away from timeline events).\r\n\r\nFor example, [this CNN test](https://www.webpagetest.org/result/180420_9P_8f26e6a35eb6fd13b6956afd4db75186/) in WebPageTest shows a little timeline activity at the beginning of the load (up until 6 seconds) and then goes silent).  \r\n\r\n![image](https://user-images.githubusercontent.com/444165/39052030-8e88e66a-4478-11e8-81bc-533dcf6d8903.png)\r\n\r\nViewing it in the [timeline viewer](https://www.webpagetest.org/chrome/timeline.php?test=180420_9P_8f26e6a35eb6fd13b6956afd4db75186&run=1) shows the same result and looking at the [raw timeline events](https://www.webpagetest.org/getTimeline.php?test=180420_9P_8f26e6a35eb6fd13b6956afd4db75186&run=1) also looks to match what the UI is showing.\r\n\r\nUp until the iOS 11.3 (Safari 11.1) release it would capture the events through the whole load.  Here is what it looks like on the iPhone 5c which is stuck at iOS 9.x:\r\n\r\n![image](https://user-images.githubusercontent.com/444165/39052198-3e1320e6-4479-11e8-9a40-30d870546126.png)\r\n\r\nHopefully it is just a new event that needs to be mapped and I'll see if I can debug it but I haven't worked on the proxy code before so it may take me a while."},"comment":{"url":"https://api.github.com/repos/google/ios-webkit-debug-proxy/issues/comments/383285156","html_url":"https://github.com/google/ios-webkit-debug-proxy/issues/256#issuecomment-383285156","issue_url":"https://api.github.com/repos/google/ios-webkit-debug-proxy/issues/256","id":383285156,"user":{"login":"artygus","id":4974968,"avatar_url":"https://avatars3.githubusercontent.com/u/4974968?v=4","gravatar_id":"","url":"https://api.github.com/users/artygus","html_url":"https://github.com/artygus","followers_url":"https://api.github.com/users/artygus/followers","following_url":"https://api.github.com/users/artygus/following{/other_user}","gists_url":"https://api.github.com/users/artygus/gists{/gist_id}","starred_url":"https://api.github.com/users/artygus/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/artygus/subscriptions","organizations_url":"https://api.github.com/users/artygus/orgs","repos_url":"https://api.github.com/users/artygus/repos","events_url":"https://api.github.com/users/artygus/events{/privacy}","received_events_url":"https://api.github.com/users/artygus/received_events","type":"User","site_admin":false},"created_at":"2018-04-21T10:58:38Z","updated_at":"2018-04-21T10:58:38Z","author_association":"COLLABORATOR","body":"oh that's interesting! let me know if you need help in debugging the issue"}}
