closing floating window with a split window closes current window

Describe the bug

When a split window (or a tab) is open, and a coc floating window pops up (for example when the cursor gets placed on a warning, or when the documentation of a symbol gets consulted), if the cursor is moved, then the current window is closed.
(see screenshot section for more clarity).

This baffles me because I had close to exactly the same nvim/coc setup on my previous work macbook three days ago, and it worked just fine: I possibly done a stupid configuration mistake, but I just cannot find it.

Reproduce the bug

• Create file mini.vim with：

  set nocompatible
  set runtimepath^=/Users/matthieu.arene/.local/share/nvim/plugged/coc.nvim
  filetype plugin indent on
  syntax on
  set hidden
  call plug#begin(stdpath('data') . '/plugged')
  Plug 'neoclide/coc.nvim', {'branch': 'release'}
  call plug#end()

• Start (neo)vim with command: vim -u mini.vim

• Open a split window, in one of those windows navigate to a warning (or hover over a documented symbol). Once a floating window pops up, move the cursor and the current window will close

Fixed on latest release branch of coc.nvim.

Ah, I feel silly now, thanks a bunch!
Out of curiosity, what precise commit did fix this? I'm asking because I installed coc on the 15th (with Plug 'neoclide/coc.nvim', {'branch': 'release'}'), so I guess it was a recent one?
