A lot of our design team need to "book out" specific issues as they prefer to work offline rather than online, so we often use a pre-made automation system that allows them to receive an email with that issues:
- Description
- Attachments (Links)
- Details (Name of Reporter, date and time created etc.)
- And most importantly, a list of all comments sent into the issue.
The problem is that when using {{issue.comments}}, the output of the comments is as below:

All I know regarding this issue is that the extra detail is due to how Jira handles signatures using PNGs and so forth. Using {{issue.comments.html}} makes it return blank. Was wondering if there's another way to have the comments come out in a more clean fashion, whilst also including: the commenter's name, time the comment was posted, and any other information.
