Thumbnails: Improve UMA coverage |
|||
Issue descriptionCurrently thumbnail capturing has very limited UMA coverage. Some things we might want to add: - How it was triggered (tab hidden vs. navigating). - Result: success, failed capture, discarded capture (new doc arrived in the meantime), couldn't start (doc hasn't painted yet); probably split by trigger.
