Table of Contents macro disappears upon refreshing the page

Issue Summary

When adding the Table of Content macros to pages, it is properly displayed once the page is being edited, published, or accessed for the first time.

However, once the page is refreshed or accessed directly via browser, the macro disappears.

Steps to Reproduce

1. Edit a page and insert the Table of Contents macro. Make sure to add headings to this page so the links will appear once the page is published.
2. Publish the page.
3. Refresh the page.

Expected Results

The macro should be displayed, including the links for headings.

Actual Results

No content is displayed where the macro should be. It disappears as soon as the page is refreshed or accessed directly via a new tab/clicking on the link to the page (externally).

Workaround

Access the page from within Confluence. For example:

• On the sidebar, click on a different page and then, click on the page with the macro again.
• Click on the page link while doing a search in Confluence.
• Tap the page from the "All updates" feed of the home page or via a macro providing a link to this page.
