Autocomplete should suggest members of sealed interface when addingg to collection

### Reproduction

Example code:

```java
package dop;

sealed interface Item {

public record Digital() implements Item {
}

}
```

```java
package dop;

import java.util.ArrayList;
import java.util.List;

public class Main {

public static void main(String[] args) {
List items = new ArrayList<>();
items.add(new Digital|)
}

}
```

Hit Ctrl+Space for autocompletion at `|` position.

### Expected

The `Digital` record gets suggested as autocomplete.
When choosing the option the import gets added as well.

### Actual

Record member doesn't get suggested.
