Description
Users can accidentally open a draft when clicking on a messages as part of their message feed navigation experience, and it can be awkward to get out of it.
We should try having the "down" arrow close an open draft when both of the following hold:
- The cursor is already at the end of the draft (so "down" has nowhere to go). This is the initial state when a draft is opened.
- The draft has not been edited since opening the compose box.
