Autocomplete doesn't work correctly on certain folder names

Steps to reproduce

    Install zsh and ohmyzsh
    run mkdir my-longfoldername-firstname  you-longfoldername-secondname
    type cd long<tab><tab>
    terminal shows "cd O-longfoldername- " instead of trying to
autocomplete.

Expected behavior

It should autocomplete like it would in case of:

    Install ohmyzsh
    run mkdir my-dir-2  your-dir-1
    type cd dir<tab><tab>
    autocomplete works as intended

How to reproduce with docker:

Create Dockerfile:

FROM ubuntu:23.04
RUN apt-get update && apt-get install -y zsh curl git
RUN sh -c "$(curl -fsSL
https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
RUN mkdir my-longfoldername-firstname  you-longfoldername-secondname
CMD zsh


Build with: docker build -t zsh-test .
Run with: docker run -ti zsh-test

cd long<tab> will produce the error while cd fold<tab><tab> works.
cd old<tab> produces another error (cd F-longfoldername-), so 0- isn't
always first character


It seems that this doesn't happen on archlinux or macOS.
POP_OS/Ubuntu seems to be affected, so this seems to be an OS dependent
issue.

Issue tested in zsh 5.8.1 and 5.9 + latest ohmyzsh
