Collapsed comments that contain only a quote

When a comment is collapsed, either through tags or already being read, it shows a one line preview of the comment. This preview skips any quotes in the comment. This works perfectly when quotes are used to reference a part of the comment they are replying to. But if the comment includes only a quote, the preview line is just blank. This makes it look like an error. I think that, if a comment has only a quote, it should do something like this:

Quote

Or

Quote: This is the quote text…
