patch 8.2.1514: multibyte vertical separator is cleared when dragging popup

Browse Source 
Problem:    Multibyte vertical separator is cleared when dragging a popup
            window using a multi-byte character for the border.
Solution:   Only clear the character before the window if it is double width.
            (closes #6766)
