`Item.rotate()` function do not rotate 'fill-gradients'?

Version: Sg: 2.9.073, Ai: 15.0.2, and the same with 'fill-patterns'.
Currently I have to write like this

```
var item = document.selectedItems[0];
item.transform(new Matrix().rotate(90, item.bounds.center),['objects', 'fill-gradients']);
```
