So, no thanks to TFA, I found the actual
bug report, and it turns out the guy went public less than 2 days after reporting the bug to Google. Talk about impatient. And it's not true that "Google issued a low-priority label to the bug when he reported it, until he wrote about it on his blog and the post started picking up steam on social media". It's true that it was originally given a low-severity label at first, it was bumped to medium a day-and-a-half later, then up to high a few hours after that--around the same time that he
went to reddit about it. Not exactly sure if it was before or after, since I don't know the timezone of the times reported on Chrome's issue tracker, but one of the comments from Google says that they had already bumped the severity rating before they knew about him going public.
