Page Properties Report macro can't display content if the Page Properties macro is placed inside an Excerpt, Expand, Section, Column or a Panel macro

Issue Summary

On the old editor, it was possible to place the Page Properties macro inside an Excerpt, Expand, Section, Column or a Panel macro macro. However, the Page Properties Report macro won't display content from this page, on its report.

Steps to Reproduce

1. Create a page (for example Test page - old editor) using the old editor.
2. Place an Excerpt, or a Panel macro on the page.
3. Place a Page Properties macro inside the Excerpt.
4. Publish Test page - old editor.
5. Add a label on the page (for example, test).
6. Create another page (for example Test page).
7. Place the Page Properties macro.
8. Publish Test page.
9. Add a label on the page (for example, test).
10. Create another page (for example, Report).
11. Place the Page Properties Report macro, and configure to use the test label.
12. Publish Report.

Expected Results

The Page Properties Report macro should display content from both pages (Test page - old editor and Test page).

Actual Results

The Page Properties report won't include content from pages in which the Page Properties macro is inside an Excerpt macro.

Workaround

Placing the Page Properties macro outside the Excerpt would fix the issue.
