JIRA Issue macros inside Page Properties Report macro don't load, spin forever instead

Summary

JIRA Issues macros that are embedded inside Page Properties macros don't load any details when they're rolled up into the corresponding Page Properties Report macro.

Environment

• Confluence Cloud (6.0.0-OD-2016.02.2 and 2016-03.01)
• JIRA Cloud

Steps to Reproduce

1. Start with a JIRA + Confluence Cloud instance.
2. In Confluence, create a page with a Page Properties Report macro on it.
3. Create another page with the Page Properties macro in it that'll show in the Page Properties Report macro above.
4. Insert a table into the Page Properties macro that contains a JIRA Issues Macro that will return some number of issues from JIRA.
5. View the original page with the Page Properties Report on it.

Expected Results

The JIRA Issues Macro that's in the Page Properties macro shows the details of the JIRA issues it's found within the Page Properties Report macro.

Actual Results

The JIRA Issues macro just sits there spinning, saying "Getting issues" and never goes further.

Notes

There's no Javascript errors in the browser console, there's no errors in the JIRA or Confluence logs, and no spike in CPU usage in JIRA or Confluence. It occurs regardless of browser. The JIRA Issues macro loads fine within the page that the Page Properties macro is on, just not the Page Properties Report macro.
