The user seeing broken PDF comments after uploading the PDF file in a Confluence page.
This is not Confluence's own "Inline Comment" feature.
- Create a PDF and add comments
- Create a page
- Add the PDF file created in step 1
- Click on the PDF file to view it
User should be able to see the PDF comments
An extended improvement would be to have PDF's Inline comment incorporated together with Confluence's Inline Comment feature on the read and write of the PDF documents.
