Backslash key and Cmd+key input not working on MacOS with Japanese Macbook about neovide HOT 2 OPEN

While discussing this issue with @fredizzimo in the discord support channel, it was suggested to use the following key remapping:

  vim.keymap.set(
      {'n', 'v', 's', 'x', 'o', 'i', 'l', 't', 'c'},
      '<M-¥>',
      '\\',
      { noremap = true, silent = true }
  )
end

I don't understand the root cause though since the log shows they key event correctly and even the return of:
text_with_all_modifiers: Some( "\", )

However, this workaround does result in the expected behavior and I am satisfied as a result.
