Not the greatest repro steps, but here's the basic setup:
- A user was navigating around various pages with column open
- On D1234, left comments and requested changes
- D1234 correctly changed to status to requires changes, but comment was missing
- Back on main dashboard, noticed that another diff D1232 had yellow bubble indicating unsubmitted comments
- It ended up being the comment that he intended to leave on D1234. It's now showing up as an unsubmitted comment D1232 instead. In the preview at the bottom, the comment is noted as "Not Visible"
We have noticed this happene twice now on our install (to a different user each time). Empirically, it seems to be correlated to the chat column being open.
