Blink cursor at top right corner's fzf 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

Should happen with every kind of config, step:
1. open nvim
2. start one of supported commands, i.e: :Files or :Buffers
3. observe blink cursor at top ~right~ left corner's fzf floating window -- I think that `block` of cursor appear in event of creating floating window and disappear right after the floating window is created but It does cause some disruptions to user while using.

Can we hide/disable that cursor at startup of floating window invoked by fzf.vim commands?

EDIT: it's top left (not top right)
