**Describe the unexpected behaviour**
Not found column number in block error when specifying ORDER BY that uses a column not mentioned in the SELECT.

**How to reproduce**
```
:) select count() over (order by number + 1) from numbers(10) order by number

Code: 10. DB::Exception: Received from localhost:9000. DB::Exception: Not found column number in block. There are only columns: count() OVER (ORDER BY number + 1 ASC), plus(number, 1)
```

**Expected behavior**
It should work.

    getRootActions(select_query->select(), only_types, step.actions());

        appendSelectSkipWindowExpressions(step, child);
