Configurations related to vim-floaterm in vimrc(i.e. g:floaterm_xxx):

"Floaterm settings
let g:floaterm_keymap_toggle = '<F12>'
let g:floaterm_width = 0.5
let g:floaterm_height = 0.5
let g:floaterm_wintype = 'vsplit'

Describe your question, feature request, or bug.

I want to use vsplit withfloaterm but when I use <f12> to close and reopen it deleted all command-line before.

But when I delete let g:floaterm_wintype = 'vsplit' and use like default, press <f12> command-line is still there.

Steps to reproduce

Using the minimal vimrc

"General settings
syntax on
set nocompatible
set background=dark
set noswapfile
set linespace=8
set textwidth=120
set shell=C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe
