Cursor disappearing (vim-sandwich)

[krissen]

At times, the cursor disappears when I use vim-sandwich command sd (surround-delete).

Using the following vimrc:

if &compatible
  set nocompatible
endif
" Add the dein installation directory into runtimepath
set runtimepath+=~/.cache/dein/repos/github.com/Shougo/dein.vim

if dein#load_state('~/.cache/dein')
  call dein#begin('~/.cache/dein')
  call dein#add('machakann/vim-sandwich')
  call dein#end()
  call dein#save_state()
endif

if dein#check_install()
  call dein#install()
endif

filetype plugin on
filetype indent on
syntax on

augroup filetypedetect
  au! BufRead,BufNewFile *.cls setfiletype tex
augroup END

let g:tex_flavor='latex'

And editing a text containing, for instance, the following: this will, no doubt, work.

Now, if I'm in normal mode and selecting the text , no doubt, and then press sd, the commas are indeed deleted --- but the cursor is also rendered invisible.

However, I can only reproduce it in vimr! (I've tried vim, nvim, gvim, and vimr.)
