Steps to Reproduce

1. In a Confluence instance linked with JIRA create a Confluence page with a table in it
2. In the header row insert a JIRA Issues Macro that refers to a specific issue
3. In the row below that (not header) insert the same JIRA Issues Macro

Actual Results

The JIRA Issues Macro in the heading spins forever and never loads.
