Know issue of list view. Tried to create a work around, it is possible, but dirty and I did not had the time to complete it. Hopefully Mendix comes up with a proper solution.
Other issue; the refresh triggers to render the list anew (with new DOM nodes). Resulting that you not only the loos the focus but also, you are scrolled back to the top.
