6d059a3 (HEAD -> main, tag: 23.07.13, origin/main, origin/HEAD) Fix bugs in insertion logic

• Operating system: macOS Ventura 13.5
• Terminal emulator: iterm2

Steps to reproduce

• git clone https://github.com/marlonrichert/zsh-autocomplete.git ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-autocomplete
• added to plugins=(git web-search zsh-autosuggestions zsh-autocomplete zsh-syntax-highlighting)
• typed: cd de
• common substring: De appears with a highlight

• I have tried disabling and enabling plugins one by one, even when zsh-autocompletion is the only plugin enabled, the highlighting is still seen

How do I remove/ change the highlighting color?

That's currently not configurable, but it could be made so.
