Describe the bug

sudo command dose not display password prompt, so I can't input password to sudo command on gvim after v8.2.2919 ( 6a43b37 ).

To Reproduce

SHELL=zsh vim -g -c 'set shelltemp' -c ':!sudo touch /tmp/foobar' -u NONE

EDIT: add SHELL=zsh

Expected behavior
I can input password to sudo command.
