This appears to be an issue with the command prompt additions that Extraterm makes in the setup_extraterm_zsh.zsh file.

If I comment out these two lines, the problem goes away:

extraterm_install_prompt_integration
add-zsh-hook precmd extraterm_install_prompt_integration

Update: narrowed it down to this line:

prefix=''`echo -n -e "%{\0033&${LC_EXTRATERM_COOKIE};3\0007%}%?%{\0000%}"`

If you change that to prefix='', the problem goes away. So it’s definitely something that’s being added to the prompt that’s causing it.

(This seems to be an issue with zsh with some other terminals too. Found this: alacritty/alacritty#1800)

To test:

Using oh-my-zsh, (e.g., Agnoster theme; although theme is not a factor):

## Before PR:

1. Open a terminal and carry out tab-completion on, say, the letter `c`
2. Notice that the `c` character is repeated.

## After PR:

Notice that the `c` character is not repeated.
