Missing Hover Effects for Layout Elements in CKEditor When Editing Existing Content

Problem/Motivation

When adding a new layout element in the CKEditor, hovering over it displays arrow icons that allow inserting a paragraph before or after the element. However, when editing an existing content item that contains a layout, these hover effects are missing.

Steps to reproduce

1. Create a new content item and insert a layout element using CKEditor.
2. Hover over the layout element and observe the arrow icons for inserting paragraphs.
3. Save the content and reopen it for editing.
4. Hover over the layout element again and notice that the arrow icons are missing.

Proposed resolution

Ensure that the hover effects and arrow icons for inserting paragraphs are also available when editing existing content with a layout element.

Remaining tasks

• Investigate why the hover effects are missing when editing existing content.
• Implement a fix to ensure consistency between new and edited content.
• Test the fix across different scenarios.

The hover effects with arrow icons should appear consistently when editing existing content.
