x-order not respected when using $ref

When using referencing, e.g.:
```
"properties": {
    "$ref": "#/components/schemas/Properties",
    "x-order": 2
},
```

Then the x-order is not respected. Only if it is put on the actual referenced feature `Properties`. 

Is this expected, or should it be possible to override the x-order value of the feature when defined directly after referencing it?
