Conflited with Oh my zsh's vi-mode

zsh-autocomplete version: 817af7c
Zsh version: 5.8 on Fedora (plus Ubuntu 20.04 and Arch)
Framework: Oh My Zsh
Plugin manager: antigen
Content of .zshrc:
```
source ~/antigen.zsh
```

antigen use oh-my-zsh antigen bundle vi-mode

antigen bundle marlonrichert/zsh-autocomplete

antigen apply



steps to reproduce

Clone master branch manually (This is not related with this issue, only to get zsh-autocomplete to work)
Install Oh My Zsh with antigen and only enable vi-mode
Down arrow key does not work at all, it cannot go to the menu
Ctrl-Space is also not working
I think it has something to do with #192 because this issue appeared only recently
