Fixes: Link Balloon closes on content with multiple richtext editors when opening the library/control room

When the Richtext-Editor, which has a CKEditor5RichTextPropertyFieldDelegatePlugin, looses focus, then the delegated value is applied. Which causes the Link Balloon to close. If the value would not change, avoid applying the value.

Fixed: CKEditor drag&drop imports contents from other systems (e.g. Content-Hub, Commerce) to the site root folder.

When drag&drop from e.g. Content-Hub, Commerce to a CKEditor contents were imported to the site root folder. Now the contents are imported to the same folder as the edited content item.
