I don't have access to file a bug through a work account for the next few days, and if you come across any issues (like CC broken by default), please file a bug with a lot of details. People do look at that stuff. I am glad that you found the source of the issue, and I hope you can agree that it would've been impossible to find it if I had just filed a bug. I do not work anywhere close to the team that implemented the CC, and when people have said "file a bug" to me in a work context, they have meant it as a way to "let's keep track of this so it's not forgotten". Luckily, the people I have met at work have been good about this. I do not speak for Google or anyone else there, just sharing my own personal experience.
