How to reproduce the problem from neovim startup

1. $ cargo new issue-rust
2. $ cd issue-rust
3. $ nvim
4. :Scratch
5. :e src/main.rs
6. Type appropriately

In this example, typing st leaves str as a completion candidate, but typing str removes str from the completion candidates.

In VSCode, completion candidates remain.
