Normally, moderators can delete comments at will. An odd exception is while reviewing the Close Votes queue, where the delete link next to comments is missing. So if I want to clean up some comments, I'm forced to open the question in a new tab and do it there. This happens a lot, and it would be a lot easier if I could clean up comments at the same time as reviewing close votes.
As this behavior is inconsistent with the rest of the site, I suspect this is unintentional, a bug.
Can you please make it possible for moderators to delete comments while reviewing the Close Votes queue?
