Extra character inserted during some completions

[rliebz]

Make sure you have done the following

• Updated to the latest version of blink.cmp
• Searched for existing issues and documentation (try <C-k> on https://cmp.saghen.dev)

Bug Description

Reproduction:

1. Open a lua file, such as repro.lua
2. On a new line, type ---@diagnostic d
3. Wait for the completion window to pop up
4. Press either <c-y> to accept or <c-n> to navigate to the next option
5. Notice that the d character appears at the end of the completion, after the cursor

A few other things I've noticed:

• This doesn't happen when completing ---@diagnostic, but it will happen when completing disable-next-line or missing-fields (as in, ---@diagnostic disable-next-line: missing-fields).
• It is always the last character that is inserted at the end, so if I type ---@diagnostic di, an i will be inserted at the end, or if I type dis, it will be an s.

Config:

-- Run with `nvim -u repro.lua`

vim.env.LAZY_STDPATH = ".repro"
load(vim.fn.system("curl -s https://raw.githubusercontent.com/folke/lazy.nvim/main/bootstrap.lua"))()

---@diagnostic disable-next-line: missing-fields
require("lazy.minit").repro({
	spec = {
		{
			"saghen/blink.cmp",
			-- please test on `main` if possible
			-- otherwise, remove this line and set `version = '*'`
			-- build = "cargo build --release",
			version = "*",
			opts = {
				sources = {
					default = {
						"lsp",
					},
				},
			},
		},
		{
			"neovim/nvim-lspconfig",
			opts = {
				servers = {
					lua_ls = {},
				},
			},
			config = function(_, opts)
				local lspconfig = require("lspconfig")
				for server, config in pairs(opts.servers) do
					-- passing config.capabilities to blink.cmp merges with the capabilities in your
					-- `opts[server].capabilities, if you've defined it
					config.capabilities = require("blink.cmp").get_lsp_capabilities()
					lspconfig[server].setup(config)
				end
			end,
		},
	},
})

Relevant configuration

sources = {
  default = { "lsp" },
}

I ran into the same issue with tailwind-css-language, looks like it's caused by this commit: ceb9f91. Rolling back to the previous commit fixed it.

@tknightz Should be fixed on that commit but I haven't tested. You ran into a slightly different issue than this one
