Description

Issue is related to: #254 The problem is resolved for the default site but still exists on additional sites.

Steps to reproduce

1. In a craft environment with multiple sites with different languages copy the content of a CKeditor field (with nested entries) from an entry on a secondary site.
2. Make a new entry on the same site and attempt to paste the content. You should see invalid entry ID errors for each of the nested entries.

Additional info

• Craft version: 5.5.0.1
• PHP version: 8.2.25
• Database driver & version: MySQL 8.2.25
• Plugins & versions: CKEditor 4.4.0
