[BUG] keymap focus / cursor desync with ToggleTermSendCurrentLine and ToggleTermSendVisualLines

### Is there an existing issue for this?

- [X] I have searched the existing issues

### Current Behavior

When opening a terminal with:
- `ToggleTermSendCurrentLine`
- `ToggleTermSendVisualLines`

The terminal opens but:
- the cursor stays in the original window.
- the "focus" moves to the terminal window.

Such as if I use `hjkl` my cursor moves inside the original window, but if I use a keymap that does `"q!"` it closes the terminal window.

The above is what happens on the first iteration. On the second iteration, the terminal window opens, but the terminal buffer is inserted into my original "document" buffer window instead of its own.

---

Alternatively: when manually running `:q`

The first iteration goes as expected: the terminal opens, my cursor is still in the window, I type `:q`, my original window closes.

The second iteration however goes exactly as described above.

### Expected Behavior

Repeated uses of the commands should open new terminal windows when needed, and the terminal windows should always go to those buffers.

It seems that even though the cursor doesn't switch windows, the keymap capture does, this should not happen.

### Steps To Reproduce

Lazy lua module:

```lua
local function make_opts(_, opts)
local custom_opts = {
open_mapping = [[]],
}

return vim.tbl_deep_extend(
"force",
opts,
custom_opts
)
end

local function make_keymaps()
return {
{
"te",
"ToggleTermSendCurrentLine 8 ",
desc = "Execute current line in a terminal.",
},
{
"te",
"ToggleTermSendVisualLines 8 ",
mode = "v",
desc = "Execute selected lines in a terminal.",
},
}
end

return {
"akinsho/toggleterm.nvim",
lazy = false,
keys = make_keymaps(),
opts = make_opts,
}
```

Sample line to execute:

```md
ls
```
