Content defined by parameter loses layout builder overrides when resaving content

Problem/Motivation

When creating content via Parameters collection, and when using a layout builder override for that specific content item, the overridden layout gets lost when resaving the content.

Steps to reproduce

Create a basic page as parameter. Use layout builder and create a custom layout for that content item. Resave the content item, for example by updating the body contents. Result: Overridden layout got lost.

Proposed resolution

Somethng is happening when the Parameters module is synchronizing the configured parameter with the saved content. Maybe the layout builder field is somewhat special and gets dropped there.

Remaining tasks

User interface changes

API changes

Data model changes
