Use attached project.

The issues appear as follow:

• after starting, click on the text item then a horizontal listview is
  displayed with the second item highlighted
• after pressing the left arrow key, the first item is highlighted but also
  the second item. (only the first item should be highlighted)
• after pressing twice the right arrow key, one can see there is a big gap
  between the "Item 3" and "Item 4"
  then comment out the line: "cacheBuffer: 800" and restart:
• after starting, click on the text item then a horizontal listview is
  displayed with the second item highlighted
• after pressing multiple times the right arrow key, when reaching the
  "item 5" the listview starts refreshing in a weird way

Those regressions have been caused by fix of QTBUG-86744.
