Summary: Ref T11114. This is a transitional change that breaks a bunch of stuff. I'll hold it until I've restored features. This stuff works: - Commenting. - Subscribers/tags/reviewers. - Pinning. - Drafts. This stuff does not work yet: - Preview of inline comments. - Probably submitting inlines, whatsoever. - Comment-area warnings like "There are failing tests." - All meaningful actions (accept, reject, etc). Test Plan: Commented on a revision. Essentially nothing else works yet. Reviewers: chad Reviewed By: chad Maniphest Tasks: T11114 Differential Revision: https://secure.phabricator.com/D17106
