Issue Summary

This is reproducible on Data Center: (no)

Steps to Reproduce

1. Create a Confluence Page containing both Team Calendar (TC) and Navitabs Macro
2. Confirm TC loads normally
3. Edit the page and move TC into the Navitabs Tab
4. Publish page

Expected Results

TC would load as it does when not nested within Navitabs macro

Actual Results

TC spins endlessly and never loads

Workaround

Editing the page and removing the TC from the Navitabs Tab Macro and publishing the page will allow the TC to work again.

Using the following query, we can identify the pages impacted:

SELECT s.spacekey
     , c.title
     , b.body
  FROM content c
 INNER JOIN spaces s ON (s.spaceid = c.spaceid)
 INNER JOIN bodycontent b ON (b.contentid = c.contentid)
 WHERE c.contenttype IN ('PAGE', 'BLOGPOST')
   AND c.content_status = 'current'
   AND c.prevver IS NULL
   AND ((b.body ~ 'ac:name="localtabgroup' AND b.body ~ 'ac:parameter ac:name="title">Team Calendar</ac:parameter')
   OR (b.body ~ 'ac:name="localtab' AND b.body ~ 'ac:parameter ac:name="title">Team Calendar</ac:parameter'))
