Loading completed: true
Frontend User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_5) AppleWebKit/602.1.34+ (KHTML, like Gecko)
Uncaught exceptions:
- TypeError: undefined is not an object (evaluating 'collectionData.affectedSnapshots') (at HeapSnapshotWorker.js:61:36)
-------
* STEPS TO REPRODUCE
1. Start a timeline recording, record a while.
2. Stop the timeline recording manually.
3. Reload the page
3. Uncaught Exception dialog when main frame finishes loading (approximately)
* NOTES
This seemed to be delayed a bit after auto-recording started. I see the initial snapshot show up in the timeline, then it throws exception soon after initial load data appears in the Timeline.</pre>
