Operating system/version

MacOS 14.2.1

Describe the bug

Floating diagnostics work fine for me, e.g. when there is a duplicate filename. The diagnostic is visible and I can jump to it with vim.diagnostic.goto_next:

However, when there is a file without any filename (obtained e.g. with D), for some reason the diagnostic float isn't showing:

and can be only invoked with vim.diagnostic.open_float:

Is this intended?

I have tried with the provided minimal config, and, weirdly, vim.diagnostic.goto_next does not show the floating window even in the first case.

What is the severity of this bug?

minor (annoyance)

Expected Behavior

As described above

Directory structure

test/test.txt

Repro

-- save as repro.lua
-- run with nvim -u repro.lua
-- DO NOT change the paths
local root = vim.fn.fnamemodify("./.repro", ":p")

-- set stdpaths to use .repro
for _, name in ipairs({ "config", "data", "state", "runtime", "cache" }) do
  vim.env[("XDG_%s_HOME"):format(name:upper())] = root .. "/" .. name
end

-- bootstrap lazy
local lazypath = root .. "/plugins/lazy.nvim"
if not vim.loop.fs_stat(lazypath) then
  vim.fn.system({
    "git",
    "clone",
    "--filter=blob:none",
    "--single-branch",
    "https://github.com/folke/lazy.nvim.git",
    lazypath,
  })
end
vim.opt.runtimepath:prepend(lazypath)

-- install plugins
local plugins = {
  "folke/tokyonight.nvim",
  {
        "stevearc/oil.nvim",
        config = function()
            require("oil").setup({
              -- add any needed settings here
            })
        end,
  },
  -- add any other plugins here
}
require("lazy").setup(plugins, {
  root = root .. "/plugins",
})

vim.cmd.colorscheme("tokyonight")
-- add anything else here

vim.diagnostic.config {
    virtual_text = false,
}

vim.keymap.set("", "]d", function() vim.diagnostic.goto_next() end)

Did you check the bug with a clean config?

[X] I have confirmed that the bug reproduces with nvim -u repro.lua using the repro.lua file above.
