    patch 9.0.0943: pretending to go out of Insert mode when Esc is received

    Problem:    Pretending to go out of Insert mode when Esc is received has side
                effects.
    Solution:   When the kitty keyboard protocol is enabled expect Esc to always
                be the start of an escape sequence.
