In the old JIRA view, when a thumbnail is embedded into the body of a JIRA ticket, when users (including those who can edit the ticket) click on the thumbnail, it displays the full image associated with the thumbnail (which makes perfect sense). One has to click elsewhere in the body to EDIT the ticket.
Whereas, in the new JIRA view, upon clicking the thumbnail brings up the EDITING mode of the ticket and NOT the full image of the picture embedded. This does not make sense and in fact leads to issues (potential unwanted edits) and delays (have to go through the attachments, match the image, click the image and remember to come back to the same location in the body of the ticket. I think we are going backwards with this. This needs to be fixed with high priority.
