Summary

When using the Chrome add-on Zephyr Capture for Jira, the images that it saves as an attachment to a Jira issue cannot be previewed from the board view.

Environment

Jira Cloud

Steps to Reproduce

• Using the Chrome add-on Zephyr Capture for Jira, take a screenshot and have it attached to a Jira issue.
• Navigate to a Jira board, either to the backlog view or the actual board view and click on the issue that has the attachment
• In the issue preview (right-hand side) locate the attachment and click on it to preview it

Expected Results

The preview will work and the image would be shown in the preview modal

Actual Results

The preview does not work and the user is prompted to download the image

Notes

1. If the user manually downloads the image and then re-uploads it, the preview works
2. The preview from the board works in the old issue view
3. Upon further investigation, it looks like the mimetype parameter of the attached image file is image/x-png. Downloading the image and then re-uploading it creates a new attachment with mimetype=image/png. With this parameter, the preview works just fine.

Workaround

1. Use the old view
2. Navigate to the issue itself by clicking the issue key. This will open the issue in a new browser tab where the preview works
