Description

When I am in the middle of autocomplete in any language (Golang/Python).

As autocomplete starts, I see another window in the background (which I am very sure are Diagnostics since I am in the middle of completing):

fmt.S][ <-- My cursor is here

Now there is a total of 3 pop ups:

1. is the menu for me to select the completion item
2. the documentation item
3. the diagnostics/lint info hiding in the background

Example: https://imgur.com/a/0JdPN8O

Steps to reproduce

Take my nvim-cmp settings from above. Try to autocomplete

Expected behavior

I should not be able to see the diagnostics hiding in the background poking out.

Actual behavior

I see the diagnostics window hiding in the background, poking out.
