[BUG] Brace completion picks wrong candidates

[tastytea]

Describe the bug

When the _approximate completer is used, the brace completion works the first time, but all other times it always picks the first candidate, regardless of what I select.

It works when the completion candidates are in the same directory, but not when they are in a subdirectory. It works without fzf-tab and with zstyle ':completion:*' menu select.

I can make sure:

• [x] I am using the latest version of fzf-tab
• [x] this is the minimal zshrc which can reproduce this bug
• [x] fzf-tab is loaded after compinit
• [x] fzf-tab is loaded after plugins which will wrap Tab, like junegunn/fzf/completion.zsh
• [x] fzf-tab is loaded before zsh-autosuggestions, zsh-syntax-highlighting and fast-syntax-highlighting.

To Reproduce

Steps to reproduce the behavior:

1. mkdir foo
2. touch foo/{a,b,c}
3. Try to get foo/{a,b,c} with completion

Expected behavior

I get what I select.

% zstyle ':completion:*' completer _complete _approximate
% source /usr/share/zsh/site-functions/fzf-tab.zsh
% mkdir foo
% touch foo/{a,b,c}
% ls foo/{a,a,a,
% zstyle ':completion:*' completer _complete
% ls foo/{a,b,c,

Log

This is a log from my normal environment, fzf-tab would not show up with C-x . in the test environment. zsh-6605-fzf-tab-1.log

Well, _approximate is not supported now: https://github.com/Aloxaf/fzf-tab/issues/56
