                   model="@load(vm.model)" rows="10" selectedItems="@bind(vm.selectedItems)">

      2. select "iPad"
      3. scroll down to select 30th item

      Current Result

      Listbox scrolls up to the first item

      Expected Result

      keep the current scroll position

      debug info

      • .z-focus-a doesn't move to the position of the selected listitem.
      • _syncFocus() in listbox-touch.js doesn't move the focus element's position but _syncFocus() in SelectWidget.js moves the position.

      attached js
