Patch 8.2.1514
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)

Edison's greatest achievement came in 1879, when he invented the
electric company.  Edison's design was a brilliant adaptation of the
simple electrical circuit: the electric company sends electricity
through a wire to a customer, then immediately gets the electricity
back through another wire
