[Bug]: Selected text was pasted twice when using the CodeCompanionChat Add hotkey

[reybits]

Pre-submission checklist

• I have read the documentation
• I have updated the plugin and all dependencies to the latest versions
• I have searched for existing issues and discussions
• My issue is not a minor or cosmetic quirk (e.g., formatting, spacing, or other non-functional details)

Neovim version (nvim -v)

v0.11.5

Operating system/version

macOS 26.2 (25C56)

Adapter and model

copilot

Describe the bug

The bug occurs even with a minimal.lua configuration that only adds keymaps for normal and visual selection modes.

Variant 1:

keys = {
    { "<leader>aa", "<cmd>CodeCompanionChat Toggle<cr>", mode = "n", desc = "Toggle Chat" },
    { "<leader>aa", "<cmd>CodeCompanionChat Add<cr>", mode = "x", desc = "Add Selection to Chat" },
},

Variant 2:

config = function()
    require("codecompanion").setup(opts)
    vim.keymap.set("n", "<leader>aa", "<cmd>CodeCompanionChat Toggle<cr>", { desc = "Toggle Chat" })
    vim.keymap.set("x", "<leader>aa", "<cmd>CodeCompanionChat Add<cr>", { desc = "Add Selection to Chat" })
end

The bug appears in both cases.

Problem:

If there are no chats currently existing (neither an opened chat window nor a hidden chat), the selected text from the buffer is sent twice when using the visual selection key map.
This is similar to the issue described in PR #2402.

Note:

If command line is used instead of <space>aa, then everything works correctly:

:'<,'>CodeCompanionChat Add

Steps to reproduce

1. Edit minimal.lua as described above, or get mine provided below.
2. Select any text and press <space>aa.

Here are the results - two code blocks and the first one without a newline character:

## Me


```lua
vim.g.mapleader = " "
vim.g.maplocalleader = " "
```Here is some code from /Users/andrey/configs/config-nvim/tmp/minimal.lua:

```lua
vim.g.mapleader = " "
vim.g.maplocalleader = " "
```

Expected behavior

I expect the selected text to be pasted once.

## Me


Here is some code from /Users/andrey/configs/config-nvim/tmp/minimal.lua:

```lua
vim.g.mapleader = " "
vim.g.maplocalleader = " "
```
