### Issue

I have two dropdowns: Category and Item.  
I need to re-build the Item dropdown’s options and set its `selectedIndex` to `0` (having the first item selected) each time I change the Category.  
xdx file attached for a quick look.  
[DROPDOWN\_TEST.xdx](https://forums.creativeclouddeveloper.com/uploads/short-url/2bKlBkRkZOJupT3bTsft7XULMWw.xdx) (5.1 KB)

### Steps to reproduce

- launch the plugin – both dropdowns are set correctly
- select another Category

### Expected Behavior

The Item dropdown is re-built and its `selectedIndex` is set to `0`. No Item’s `onchange` event detected.

### Actual Behavior

The Item dropdown is re-built but its `selectedIndex` is set to `-1` (unselected state). Its `onchange` event is triggered.

### Additional information

This happens on **Windows only**. On Mac all works fine.  
It seems that the only way is to remove the Item dropdown then create it from scratch each time a Category has changed (uncomment code at lines 125-133)
