vim.lsp.buf.format() scrolls window on nightly

[TymekDev]

Hey, I have just noticed that commit 9b9030f introduces an unexpected window scrolling. Whenever I call vim.lsp.buf.format() I end up with window scrolled as if I used zb.

CleanShot.2023-09-26.at.09.51.06.mp4

This appears to be affected by both scrolloff and window size. If the window contains fewer lines, then it does not necessarily happen.

Config for reproduction:

-- lazy.nvim bootstrap start
local lazypath = vim.fn.stdpath("data") .. "/lazy/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",
    "--branch=stable", -- latest stable release
    lazypath,
  })
end
vim.opt.rtp:prepend(lazypath)
-- lazy.nvim bootstrap end

require("lazy").setup({
  {
    "neovim/nvim-lspconfig",
    config = function()
      require("lspconfig").r_language_server.setup({
        cmd = { "R", "--vanilla", "--slave", "-e", "languageserver::run()" },
      })
    end,
  },
})

Some follow-up changes has been merged to the bisected PR. Please try again and see if the behavior makes sense now.

@bfredl looks good! I cannot reproduce the issue anymore.
