Messy prompt

[mooreye]

This is my .bashrc fragment relevant to hstr:

if [[ $- == *i* ]]; then
    _hstrnotiocsti() {
        { READLINE_LINE="$( { </dev/tty hstr "${@:-}" $READLINE_LINE; } 2>&1 1>&3 3>&- )"; } 3>&1
        READLINE_POINT=${#READLINE_LINE}
    }
    export HSTR_TIOCSTI=n
    export HSTR_CONFIG='blacklist,hicolor,help-on-opposite-side,raw-history-view,static-favorites'
    export HSTR_PROMPT='> '
    bind -x '"\C-r": _hstrnotiocsti --'
    bind -x '"\C-s": _hstrnotiocsti -f'
fi

This is what happens when you type, backspace and then type again:

you can see characters randomly disappear in the prompt.
