Jump back (i.e. ctrl-o) is broken after hop (at least :HopChar1)

[idevat]

Describe the bug
The cursor is on the position P. Use :HopChar1 to hop somwhere and the ctrl-o to jump back. Cursor is not on the original position P.

To Reproduce
Configuration:

local root = vim.fn.fnamemodify("./.repro", ":p")

-- set stdpaths to use .repro
for _, name in ipairs({ "config", "data", "state", "cache" }) do
  vim.env[("XDG_%s_HOME"):format(name:upper())] = root .. "/" .. name
end

-- bootstrap lazy
local lazypath = root .. "/plugins/lazy.nvim"
if not vim.loop.fs_stat(lazypath) then
  vim.fn.system({ "git", "clone", "--filter=blob:none", "https://github.com/folke/lazy.nvim.git", lazypath, })
end
vim.opt.runtimepath:prepend(lazypath)

-- install plugins
local plugins = {
  { "smoka7/hop.nvim", opts = {} },
}
require("lazy").setup(plugins, {
  root = root .. "/plugins",
})

Steps to reproduce the behavior:

1. Let's have a file with simple content:

first
second
third

2. Put the cursor on the first line on character r.
3. Run :HopChar1, use character i, so you get two targets (a in the word first and s in the word third) - choose s
4. Press ctrl-o to jump back
5. You are on character f in the word first

Expected behavior
After jump back by ctrl-o, you should be on the character r in the word first - the place before hop.

Version (please complete the following information):

• Nvim version: 0.9.1
• hop.nvim version: master

Additional context
Additionally - in the more complex content, the cursor is not even on the same line after ctrl-o.

Thank you for maintaining hop.nvim after the original project become unmaintained. However, after switch to this repo this issue appeared. It breaks e.g. following workflow: hop somewhere, cut/yank some content, jump back and put the content there.

Thanks for the report, it's a bug in upstream neovim/neovim#17861 .
The original code used vim.cmd("normal! m'") and when I changed it to new api I wasn't aware of ctrl-o and only tested it with ``.
Maybe we should revert it till that issue gets fixed.
