Steps:


1. Run HelloTextArea
2. Delete all text in there
3. Hit return, type "whatever", hit enter again
The text in the control should be "\nWhatever\n"

Now use arrow up, note that as the cursor navigates the second line ("Whatever") the caret is placed at the end of the line, it should be at the start. The same happen if you start from the top and use arrow down to get to end.

Compare to any editor you like (mac, windows, etc)
