What happened?

I have encountered an issue with the Landing Page Builder in Mautic. When I edit a landing page and switch to the code edit mode in the GrapeJS builder, parts of the <head> content are duplicated into the <body> section after saving. This behavior repeats every time the page is saved while in this mode, resulting in additional duplications with each save.

How can we reproduce this issue?

Step 1: Create a new landing page using the “Blank” theme or a custom theme.
Step 2: Switch to the code edit mode and click save.
Step 3: Repeat switching between code edit mode and saving: The duplicates increase with each save.
Result: The <head> content (e.g., <meta> tags or <title>) is duplicated into the <body> section.

Expected Behavior: The <head> content should remain within the <head> section, as defined in the base.html.twig or other relevant templates, and should not be duplicated into the <body> section after making changes using the code edit function in the GrapeJS builder.

Actual Behavior: Parts of the <head> content, including <meta> tags and <title>, are repeatedly copied into the <body> section of the generated HTML page.

Additional Information: This issue occurs with the default “Blank” theme, which indicates that it is not directly related to custom HTML or themes. It seems to be an issue with how the HTML code is processed in the editor.
