Issue Summary

Confluence flickers between two layouts when creating a new page with a long title in maximized Chrome (Windows) with the sidebar positioned to hide the page title and path. This issue appears related to BreadcrumbsQuery calls.

This is reproducible on Data Center: (yes) / (no)

Steps to Reproduce

1. Enable portrait (flipped) screen orientation
2. Open Chrome (Windows) and maximize the window.
3. Start creating a new Confluence page.
4. Position the sidebar to completely hide the page title and path.

Expected Results

The Confluence draft page displays consistently.

Actual Results

The Confluence draft rapidly flickers between two different layouts.

This issue may be related to BreadcrumbsQuery calls observed during the flickering.

Workaround

Slightly adjust the sidebar position to expose part of the page title or path. This seems to stop the flickering behavior.
