[Storyboard] Duplicated pages cause unexpected re-renders and inconsistent page

[gbergengruen]

Preliminary Checks

• I have read and understood the important section above.
• I have searched existing issues and avoided creating duplicates.
• I am filing a bug report, not a feature request.

What happened?

After duplicating a page and editing one of the copies, the system appeared to re-render multiple related pages. Changes made to one copy could trigger rendering activity on other duplicated pages, making it difficult to predict which version would be preserved and creating uncertainty during editing.

Expected behavior

Editing a duplicated page should only affect that page unless explicitly linked.

Actual behavior

Changes to a duplicated page trigger re-rendering of multiple related pages.

Steps to reproduce

1. Open a page in Storyboard.
2. Duplicate the page.
3. Modify content in one of the copies.
4. Navigate between duplicated pages.
5. Observe that multiple pages enter a rendering state or receive unexpected updates.
