Weird behavior in interactive menu completion

[Programmer <linux.dev25@xxxxxxxxx>]

Hello,

I have a question about unusual menuselect behavior in interactive menu 
completion.

Steps to Reproduce:

zsh -f
zmodload zsh/complist
builtin zstyle ':completion:*' menu select=0 interactive

autoload -Uz compinit
compinit

% zs<tab;tab>;pwd

Move cursor to position.  Press tab 2x to get into interactive menu 
completion.  Then press any arrow key.

Expected:

zsh;pwd after interactive menu completion selecting zsh

Actual:

Characters to right of cursor are discarded such as ';' in this 
example.  Exact amount that are discarded seems to be length of first 
item in menuselect - prefix length.

For example, current line becomes zshpwd instead of zsh;pwd when 
selecting zsh in menucompletion.

This does not occur with regular (noninteractive) menu completion.


Thanks,

Jacob
