Issue Summary

In Confluence Cloud, when the root page title of a Page Tree macro contains an emoji, the macro fails to load and displays an error message: "The selected root page could not be found".

Steps to Reproduce

1. Create a new root page in Confluence Cloud.
2. Set the page title to include one or more emojis (e.g., "📕 Book").
3. On a new page, add a Page Tree macro.
4. Set the root page of the Page Tree macro to the newly created page with the emoji in the title.
5. Publish the page.
6. Observe the error message: "The selected root page could not be found."

Expected Results

The Page Tree macro should load correctly, displaying the page tree structure starting from the root page with the emoji in the title.

Actual Results

The Page Tree macro fails to load and displays the error message: "The selected root page could not be found."

Workaround

• Remove the emoji from the title of the root page.
• Create a new Page Tree macro with the root page that no longer contains the emoji.
• Publish the page. The Page Tree macro will now work and display the page tree structure as expected.
