Summary:
Ref T7062. When we load a thread, we always show the column, even if it has been closed between the time we sent the request and when we're processing the response.
Normally this isn't a big deal, but it can specifically show up on mobile.
(This load also shouldn't be happening at all, but I'll fix that separately.)
Test Plan: Mobile no longer shows the column after it loads.
