Is there an existing issue for this?

Summary

Open images 🖼️ in full screen mode once one clicks on an attachment or - especially - when one clicks on images in the comments section. If I'm not mistaken, if nothing currently happens when we click on such images within comments.

Why should this be worked on?

In order to properly see the images teammates leave on their Issues and I have to open them on a new screen. It would be great if the user could see attachments in full screen without leaving the Issue.

upvote. This is really annoying right now when we need to post a image in the comment section.

This is definitely a great feature to have, we'll try to ship it soon.
