Last line is sometimes not rendered

[simonmandlik]

I have noticed that the column on the last line is sometimes rendered and sometimes it isn't.

MWE:

local root = vim.fn.fnamemodify("./.repro", ":p")
for _, name in ipairs({ "config", "data", "state", "cache" }) do
  vim.env[("XDG_%s_HOME"):format(name:upper())] = root .. "/" .. name
end
local lazypath = root .. "/plugins/lazy.nvim"
if not vim.loop.fs_stat(lazypath) then
  vim.fn.system({ "git", "clone", "--filter=blob:none", "https://github.com/folke/lazy.nvim.git", lazypath, })
end
vim.opt.runtimepath:prepend(lazypath)

local plugins = {
    spec = {
        {
            "lukas-reineke/virt-column.nvim",
            opts = {
                virtcolumn = "+1,+2,+3",
            },
        },
    }
}

require("lazy").setup(plugins, {
    root = root .. "/plugins",
})

vim.opt.textwidth = 10

Run nvim -u repro.lua.

1. In insert mode, write return {\n}. This leads to this:

2. In empty file again, write return {\n\n<BS>} in insert mode. This gives me:

Two buffers are identical, but virtual column is different
