Finding suitable reviewers
The code in DevTools is divided into modules (because there's just so much code it's impossible for one person to know everything off the top of their head).
Each module has one or more "owners", who know a lot about it. And they're the people you want to ask to review your code 😀
You might already know who is the reviewer (perhaps the person that is mentoring the bug, perhaps your team mate), but in case of doubt, you can consult this list of people and modules.
