Vim `completeopt`'s `noselect` doesn't work

Warning: I will close the issue without the minimal init.vim and the reproduction instructions.

Problems summary

I followed the documentation to setup ddc.vim, and the FAQ section about “auto select behavior” says to use set completeopt+=noselect.

As seen in the image, even with this option set (I ran :set completeopt), the first popup menu item is not selected.

Expected

The first popup menu item to be selected (auto select behavior)

Provide a minimal init.vim/vimrc without plugin managers (Required!)

call ddc#custom#patch_global('sources', ['vim-lsp'])
call ddc#custom#patch_global('sourceOptions', {
  \ 'vim-lsp': {
  \   'matchers': ['matcher_fuzzy'],
  \   'mark': 'lsp',
  \ }})

set completeopt+=noselect

" Use ddc.
call ddc#enable()

How to reproduce the problem from neovim/Vim startup (Required!)

1. Get any completion, the first item is not selected when the popup menu shows up

Oh, no…

So I have said I think you have not test the minimal vimrc.

[haze]

And you should check completeopt value by verbose set completeopt?.

Thank you so much! This helped me figure out what was overriding my completeopt. I also had asyncomplete installed. Sorry for wasting your time, but thanks for teaching me something new 😃
