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.
