Apparently the "Files changed" tab works differently now. I navigated to the tab and now instead of `/files` it goes to `/changes`. It looks very similar except:

It shows me 1 file at a time. I cant scroll to see everything. I cant even search the diffs. It's maddening. I can still see all files on smaller PRs.

Seems like maybe its set by a viewcontent.github.com cookie but it re-appears everytime I delete it while logged in. If I try to navigate to `/files` it redirects to `/changes`. Definitely tied to user account. I can still see the old `/files` page when not logged in. Can't find anything about this elsewhere.
