Non-nil if Icomplete-Vertical mode is enabled.
See the icomplete-vertical-mode(var)/icomplete-vertical-mode(fun) command
for a description of this minor mode.
Setting this variable directly does not take effect;
either customize it (see the info node (emacs)Easy Customization)
or call the function icomplete-vertical-mode(var)/icomplete-vertical-mode(fun).
Probably introduced at or before Emacs version 28.1.

If none of these modes are on, turn on `icomplete-mode'.
As many completion candidates as possible are displayed, depending on
the value of `max-mini-window-height', and the way the mini-window is
resized depends on `resize-mini-windows'."
