patch 9.2.0596: cmdline completion popup cannot be scrolled with the mouse
Problem: In command-line completion with a popup menu ('wildoptions'
contains "pum"), the info popup shown next to the menu could
not be scrolled, unlike the Insert mode completion info popup
which scrolls with the mouse wheel.
Solution: When the mouse pointer is on top of the info popup, scroll it
with the mouse wheel in command-line mode as well, without
closing the completion popup menu.
