Wrong initial index in RightToLeft Horizontal ListView

Horizontally mirrored ListView doesn't apply correct index.

Bug is was reproduced on Qt 5.12, 5.15

 
>>>>>>>>>>>>>>>>> LeftToRight correctly applies index#3

ListView {

 orientation: ListView.Horizontal

 layoutDirection: ListView.LeftToRight

 model: ["0", "1", "2", "3", "4", "5", "6"]

 currentIndex: 3

}

 
>>>>>>>>>>>>>>>>> RightToLeft DOESN'T apply index#3, index#0 is displayed instead

ListView {

 orientation: ListView.Horizontal

 layoutDirection: ListView.RightToLeft

 model: ["0", "1", "2", "3", "4", "5", "6"]

 currentIndex: 3

}
