Created attachment 468263 [details] Timeline recording missing worker events Worker thread info does not appear to show up in any Timeline views other than CPU usage. Some initial discussion in the slack WebKit#web-inspector-help and initial findings and basic repro case from Razvan Caliman : https://webkit.slack.com/archives/CU80T42P9/p1696870632997349 Repro case: 1. Navigate to https://mdn.github.io/dom-examples/web-workers/fibonacci-worker/ (source code: https://github.com/mdn/dom-examples/tree/3e75d616aba9c98c2b31c269e7e28089ffe43529/web-workers/fibonacci-worker) 2. Open Web Inspector>Timelines and start recording a profile. 3. Enter a number in the input field and click submit (worker thread will execute the calculation via fibonacci.js). 4. End recording Expected: JavaScript & Events should show that the fibonacci function (or worker onmessage) ran. Actual: JavaScript & Events only originating from the UI thread show up. Timeline recording going through the above steps is attached. Safari Version 17.0 (19616.1.27.211.1)
