nvim_cmp: can't cycle through suggestions

### 🐛 Describe the bug

I can't seem to cycle through suggestions. My keybinding will only let me choose one, and then I see a flicker.

See the attached video for more context:

Start by reproducing the reported completion behavior with the provided nvim-cmp mappings, especially and , using the listed Neovim and obsidian.nvim versions. Compare the behavior with the supplied Obsidian.nvim configuration and determine whether the flicker is caused by the plugin integration or nvim-cmp. Done means completion suggestions can be cycled without selecting only one item or flickering.
