While performing <C-n> on the selection
Do you think this is related to this PR or I am looking at the wrong place?

Should I open an issue or can I keep commenting on this thread?

Edit:
I'm using LazyVim distro and haven't changed anything related to cmp on my config

Edit2:
Confirmation: reverting back to 7e348da cleared the issue

Same issue, after updating nvim-cmp. Solved with a rollback to the mentioned commit, ty for the time saved!

Seems like there may be an issue on the last commit:
e1757ae feat(view): add api get_selected_index (#1986) (8 hours ago)

@MichFe Please test #1993.
