Stop timeline => Scripts Timeline does not show the promise handler * NOTES Likely places to look are: - JSJobMicrotask::run - JSJob.cpp - JSPromiseDeferred::resolve and JSPromiseDeferred::reject - JSPromiseDeferred.cpp - JSInternalPromise::then - JSInternalPromise.cpp 1143199 1 webkit-bug-importer 2015-11-18 22:33:50 -0800 <rdar://problem/23607399> 1148031 2 joepeck 2015-12-09 18:56:00 -0800 I am addressing this in bug 151899. *** This bug has been marked as a duplicate of bug 151899 *** 1148035 3 joepeck 2015-12-09 18:57:29 -0800 To be clear that bug profiles it in ScriptProfiler, it won't yet show up in a Page inspection until we move Page inspection to using ScriptProfiler.
