Thank you for your contribution! When addressing review feedback, please adhere to the following:

• Please update your pull request according to feedback until it is approved by one of the core team members.
• Apply suggested changes directly so the reviewer doesn't have to eyeball the changes. These resolve themselves after applying them, and that's fine.
• Don't resolve other conversations so it's easier to track for the reviewer. Then, the reviewer will resolve them.
• Feel free to mark conversations that you addressed to keep track of them with an emoji or otherwise, just don't resolve them.
• Please keep conversations happening in line comments in those convos, otherwise, communication will be a mess. If you have trouble finding them, see this video.
• When you're done addressing all feedback of a review, click "Re-request review" in the top-right corner for each reviewer when you're ready for another round of review, so they know that you're done.

Please merge next time instead of opening a new PR. This adds needless friction, since I now need to review the whole PR again, not just the recent changes.
