What happens in the case where two comments are optimistically added, then
the first one fails?
e.g.
1. User adds comment_1
2. User adds comment_2
3. Some failure occurs and comment_1 fails, but comment_2 succeeds.
I'd expect the state of this to be just comment_2. Since the UI stores the
previousComments, does this get overwritten by adding comment_2? In this case,
and correct me if I'm wrong, the comments will be reset to the UI's belief of
the previous version (comment_1) and therefore out of sync with the store until
the comments are reloaded.
Admittedly, I'd expect this to be pretty rare (and require the user to
rapidly add a couple comments)
