Nesting complex macros inside of a user macro breaks page rendering

Issue Summary

When we create a user macro and use a Task report and an Expand macro inside the user macro, it breaks page rendering.
It only happens when the task report include tasks.

This is reproducible on Data Center: Yes

Steps to Reproduce

Step-1. Create the user macro.

• Macro Name: anymacro
• Visibility: Visible to all users in the Macro Browser
• Macro Title: anymacro
• Macro Body Processing: Rendered
• Template: Attached: macro_template.rtf

Step-2. Create a new page and nested a Task report and an Expand macro inside the user macro.

Step-3. The Page Tree is not rendering anymore after publishing. Profile picture also shows broken. Attaching the Storage format of the impacted page: storage_format.rtf

Expected Results

Page Tree and Profile picture should render.

Actual Results

Page Tree and Profile picture does not render post publishing.

Workaround

Currently there is no known workaround for this behaviour. A workaround will be added here when available.
