[forty-cdk/listbox] FORCDK-LISTBOX-002: ForListboxGroupLabel must be used inside a [forListboxGroup] element.
Cause
No ForListboxGroup provider is visible from ForListboxGroupLabel. Angular resolves a directive's dependencies at the template's declaration site rather than where it is stamped, so a piece declared in an ng-template outside the root resolves nothing even when it renders inside it.
Fix
Move ForListboxGroupLabel inside a [forListboxGroup] element, declaring any ng-template it lives in there too.
