Issue Summary

Epic Link in Jira Issue Macro that connects to Jira Cloud not showing Lozenge Color and Hyperlink when Epic Name and Epic Summary are not the same.

This is reproducible on Data Center: Yes

Steps to Reproduce

1. Install Confluence Server/DC and configure Application Link with Jira Cloud
2. In Jira Cloud:
   • Create Epic that has different Epic Name and Epic Summary
     
   • Create story that link to the Epic above
3. In Confluence Server/DC:
   • Insert a Jira Issue Macro that shows the story created above
   • Make sure Epic Link field is configured to show in the macro
4. View the Confluence Page with Jira Issue Macro

Expected Results

Epic Link should:

• show as Epic Name
• have the correct colored lozenge
• have the correct hyperlink to it's Epic

Actual Results

Epic Link is:

• show as Epic Summary
• not showing as lozenge
• not having any hyperlink

Information

The same issue does not happen when Confluence Server/DC is retrieving same set of data from Jira Server/DC.
This is because the XML Response from Jira Cloud did not provide the unique Issue Key for Epic Link, but Epic Summary instead.

While this has the same outcome as CONFSERVER-91469, but the cause are different

Workaround

In Jira Cloud, set the Epic Summary and Epic Name to be the same exact value.
