Canvas layout resets settings during use of horizontal scrolling

When using the Canvas layout in combination with horizontal scrolling, the page frequently resets partially after closing the editor or switching between edit and preview modes.

This results in multiple layout settings being changed or lost without user input.

Examples of affected settings include:

- Background color

- Horizontal / vertical orientation

- Overall layout size

- Layout position

- Lightbox (enabled/disabled)

- Section width and padding

Expected behavior:

All layout settings should persist consistently after switching modes or reopening the page.

Actual behavior:

Various layout settings reset randomly, causing loss of work and requiring repeated adjustments.

Impact:

This is a critical issue, especially for complex layouts, as it can result in significant time loss and repeated manual reconfiguration.
