Subject: vim-patch:8.2.4504: when there is a partially matching map full map
 may not work

Problem:    When there is a partially matching map and modifyOtherKeys is
            active a full map may not work.
Solution:   Only simplify modifiers when there is no matching mapping.
            (closes vim/vim#8792)

Omit test as it sends terminal codes. Use a Lua test instead.
