Bug ID: 47305
           Summary: Notepad doesn't adjust caret and scroll position
                    properly
           Product: Wine
           Version: 4.9
          Hardware: x86
                OS: Linux
            Status: NEW
          Severity: normal

This is just to track the issue here, I'll send in a patch soon. Found on
https://jira.reactos.org/browse/CORE-15780.

Issue description from ReactOS JIRA:

How to reproduce:

Open Notepad
Make sure you disabled word wrapping (it usually disabled by default)
Type in very long string to activate horizontal scroll bar
Make a new string (hit Enter)
Now your caret position would be somewhere at the beginning of line 2, but the
whole text box is not scrolled to the first character position, and horizontal
scroll bar position is not changed (see attached screenshot).

If you move your caret back to line 1 ending, and move with arrow keys to line
2, the bug will appear again (it does not matter whether right or down arrow
key will be used).
