Item - detail bug when grid has parent component

[kravcik]

The problem occurs when a Grid is used in the component. The item detail view stops working because it no longer matches the full name. I'm not sure what the right approach is yet, but as a temporary workaround, the following Composer patch can be used to alter the code.
