can't exit fzf when clicking outside of floating window

- [x] I have fzf 0.30.0 or above
- [x] I have read through https://github.com/junegunn/fzf.vim/blob/master/README.md
- [x] I have read through https://github.com/junegunn/fzf/blob/master/README-VIM.md
- [x] I have read through the manual page of fzf (`man fzf`)
- [x] I have searched through the existing issues

I'm using neovim and when I use the mouse to click outside of the floating fzf window the focus is back in the editor but the fzf window is still visible.
It can't be refocused by clicking on it and has to be [killed forcefully](https://www.reddit.com/r/neovim/comments/nrz9hp/can_i_close_all_floating_windows_without_closing/h0lg5m1/)
