Description

I am trying to migrate an application that uses Taiga UI 3.89 to version 4.0.

After running the migrations and resolving the //TODO cases that were added to the code, there are still some errors that seem to come internally from the framework.

When building a production build I get this error:

X [ERROR] TS2416: Property 'items' in type "TuiDataListGroupWrapperComponent<T>" is not assignable to the same property in base type "TuiDataListWrapperComponent<T>".
  Type "readonly T[][]" is not assignable to type "readonly T[]".
    Type "T[]" is not assignable to type "T".
      "T" could be instantiated with an arbitrary type which could be unrelated to "T[]". [plugin angular-compiler]
