Bug: character following inserted text is deleted

[chrisgrieser]

Make sure you have done the following

• Updated to the latest version of blink.cmp
• Searched for existing issues and documentation (try <C-k> on https://cmp.saghen.dev)

Bug Description

I noticed this issue when using blink-cmp-git: Kaiser-Yang/blink-cmp-git#60

# original text with `|` marking the cursor position.

# EXAMPLE 1
foobar (|)

# I type `#`, select and confirm an issue that is inserted. Result:
foobar (#123

# expected result
foobar (#123)

# EXAMPLE 2
Foobar | Hello World.

# I type `#`, select and confirm an issue that is inserted. Result:
Foobar #123llo World.

# expected result
Foobar #123 Hello World.

reproduce via:

-- save as `minimal-config.lua`
-- run via: `nvim -u minimal-config.lua`

At first, I thought this was a bug related to blink-cmp-git, since this issue did not occur for me with any other sources. However, @Kaiser-Yang (the creator of blink-cmp-git) noted that the issue is in fact caused by blink itself.

Relevant configuration

happens with default config (+ blink-cmp-git)

neovim version

NVIM v0.11.2 Build type: Release LuaJIT 2.1.1748459687

blink.cmp version

1.4.1

Is this #1736 ? In that case, it's not specific to Rust's language server but to blink?
