Incorrect navigation by QListView if isWrapping property enabled

In situation when the QListView have several columns (i.e. isWrapping=true) and selected last item in column user don't have ability to navigate on the next item (in next column) use "Down" key.

Steps for reproduce

1. Compile and run test project from attachment (I use QListWidget instead of QListView for simplify demonstration)
2. Select last item in first column (i.e. New Item #4).
3. Click "Down" button on keyboard

As you can see do nothing.

Expected behavior

Next item should be selected (i.e. New Item #5).

As you understand user also should have ability for move from "New Item #5" to "New Item #4" use "Up" button.
