[BUG] toggleterm changing terminal width strangely with `signcolumn = "yes"`

[wenjinnn]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

When setting hide_numbers = true and have vim.opt.signcolumn = "yes", open some full screen app, it renders beyond the screen, e.g. lazygit

and if I press tab to switch to next lazygit window, It will looks like:

this happened after I upgrade to nvim 0.10, now I'm setting hide_numbers to false, and add a on_open hook to achieve the same behavior and it work well:

        on_open = function()
          local ol = vim.opt_local
          ol.number = false
          ol.signcolumn = "no"
          ol.relativenumber = false
        end,

Expected Behavior

Work like normal terminal

Steps To Reproduce

1. Toggleterm with direction horizontal, not sure if other direction have the same issue
2. Have vim.opt.signcolumn = "yes"
3. Open toggleterm and run lazygit in terminal

Environment

- OS: NixOS 23.11
- neovim version: 0.10
- Shell: zsh
