Hello,

I've seen several issues about the working directory getting changed in Neovim, that were fixed by https://github.com/junegunn/fzf/commit/cd59e5d07b3a69a75f7c0d02efd66b6f04bb13a1#diff-24d9d57e35df5afce7890f2400917919

However, when I run `:FZF`, select two entries, and open them in multiple tabs, only the first file gets opened, the other is just an empty buffer.

This is because the current directory got modified, but was not restored as `:pwd` showed me.

`set autochdir?` returns `noautochdir`. I did not see any options in my `init.vim` that were relevant to this issue.

I also use `FZF_DEFAULT_COMMAND='ag -g ""' in my zshrc
