Summary

When displayed in a content by label macro, the links to PDF attachments do not open in a preview light box but rather are immediately downloaded.

Environment

Confluence 6.2.3

Steps to Reproduce

1. Attach a PDF to a page
2. In the attachment properties, add a label
3. Insert a content by label macro, specifying the label that was added to the attachment
4. Save the page
5. Click the link to the attachment which is displayed in the content by label macro

Expected Results

The PDF would preview.

Actual Results

The PDF is downloaded when you click on the link.

Notes

This is inconsistent behavior because .png images do preview when you click their links that are displayed in the content by label macro.

Workaround

No workaround at present.
