steps to reproduce:
1. git checkout -b cats
1. git add cat.jpg
1. git commit -m "cats!"
1. arc diff master --verbatim
1. open Revision
1. add comment to image
1. submit
1. reload Revision
1. try to mark the comment as Done, click reply, or in any other way interact with the comment
expected result: I expect the comment on the image to function exactly like comments on code files do, as it appears exactly the same
reality: clicks on any part of the comment don't do anything. the Done checkbox gets its "active" state but on release doesn't switch to "selected" state. Javascript console is full of `core.pkg.js:2 Uncaught Error: JX.$('C2535NL1') call matched no nodes.` errors that get triggered on mouseenter/mouseleave and click events
