ListView : MouseEvents are receieved differently depending on datatype present in listview

Run the attached test.

Make sure that listview is focused (blue boarder around it) and none of the items are selected (Remove selection by pressing CTRL-\ (backslash).

Now move the mouseinside when the contents are strings only, you will observe that the event text (first line) doesn't change. Now press left arrow key to change the content to textbox. Now again move the mouse inside listview. See the content of the event text changes from mouseentered to mousexited and so on.

The sequence of events received should be same for listview irrespective of content if none of the items are selected.
