Group fieldtype has no visual indicator if it cannot be located in a multisite

[helloDanuk]

Bug description

Correction: In addition to the issue described here, it is also not possible to localize the Group fieldtype if you try to do. You cannot save different field values in the second language. It jumps back to the origin value after saving.

Original issue: Use a group fieldtype in a multisite. The group is not localized, but you are able to edit the content in the second language (in the example a text field and toggles). Although the origin values are restored after saving, the fields in the second language should never be editable.

How to reproduce

• Create a not localizable group fieldtype, add a couple of fields.
• Edit the group content in origin
• Change to second language
• Edit the same content (which should not be possible) and save again.
