1. Run HelloTextArea
2. Delete all text in there
3. Type "abcd", [enter key], "ef" (the text in the control "abcd\nef")

4. At this point the care after "f", use left arrow to move the caret between "cd".
5. Arrow down (the caret again will be after "f")
6. Again use left arrow to the caret between "cd".

Note that caret will not stop in front of "e" (it jumps), and it takes two strokes to move from after "d" to between "cd".
