Most of this code is already dead. The native appearance on macOS doesn't work on dark mode, and on Windows and Linux we are already overriding it. Add a first-column tree property to be able to align the inner borders on macOS properly. Differential Revision: https://phabricator.services.mozilla.com/D206526
