Undo resets cursor position at the top of the file

[notpeelz]

Describe the bug Pressing u in normal mode after generating the documentation will reset the cursor position to the top of the file. I've only tested this with typescript files.

To Reproduce

• Create file doge.vim with:

set nocompatible
set runtimepath^=/path/to/vim-doge
filetype plugin indent on
syntax on
set hidden

• Start neovim with command: nvim -u doge.vim

Steps to reproduce the behavior:

1. Type :set ft=typescript
2. Enter insert mode and paste this code:

const a = 5;  

function blah(value: number): number {
  return 4;
}

3. Move your cursor to the 3rd line and press <Leader>d
4. Press <Escape>
5. Press u

Expected behavior

I expected my cursor to go back to the last location before generating the documentation.
