long wrapped line at bottom won't visually unselect

[kevinlawler]

Describe the bug

Visually selecting from the bottom up, while wordwrap is on, and then unselecting still leaves the appearance of selected text if the last displayed line extends beyond the length of the window.

To Reproduce

0. Load this file long.txt
1. :set wrap
2. :set display+=lastline
3. :set lines=25
4. :set columns=69
5. Scroll to bottom, move cursor to last character. Using v, enter visual mode and select from the bottom of the file to the top. Scroll to top, select to first character. Last line should extend beyond the length of the screen.
6. Unselect using <Esc>
7. Observe artifact (Done)
8. <C-L> to clear

Expected behavior
Appearance of selection should not be there

Some pieces are missing. At least need to set 'display' to "lastline".
Please start with "vim --clean".
Also mention how you move to the position where you start Visual mode (for me it makes the whole line appear).
