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

### Is there an existing issue for this?

- [X] 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
