Description

See: Steps to reproduce.

Steps to reproduce

(1) Files used to reproduce error.

> ls
minimal-init.vim  test.vhdl

(2) Bare minimum VHDL file with preamble only.

> cat test.vhdl
library ieee;
use ieee.std_logic_1164.all;
use ieee.numeric_std.all;

(3) Open test.vhdl with nvim using the minimal config.

> nvim -u minimal-init.vim test.vhdl

(4) Create a new line at the bottom of the file. Start inserting iee and let cmp-buffer suggest ieee from the nvim-cmp drop down menu. Select ieee from the drop down menu and use <CR> to call cmp.mapping.confirm({ select = true }) from the minimal config.

(5) Observe.

Expected behavior

Normal autocompletion, as it works for all other filetypes, beside the VHDL file type.

Actual behavior
