I see this occasionally. ------- Auto-generated details: Inspected URL: http://www.apple.com/watch/ Uncaught exceptions: - TypeError: undefined is not an object (evaluating 'imageElement.classList') (at HeapAllocationsTimelineOverviewGraph.js:112:21) _updateSnapshotMarkers @ HeapAllocationsTimelineOverviewGraph.js:112:21 updateSelectedRecord @ HeapAllocationsTimelineOverviewGraph.js:95:36 ? @ TimelineOverviewGraph.js:248:38 ------- * STEPS TO REPRODUCE 1. Inspect apple.com/watch/ 2. Start a timeline recording and stop 3. Add Allocations timeline 4. Wait 10 seconds so a new recording would be offscreen of the overview graph 5. Take a heap snapshot 6. Go into that heap snapshot => Exception * NOTES I think the issue here is that the snapshot doesn't have an image element in the overview graph, so we should have bailed earlier.
