Limiting the length of the string literal makes wrong completion

[STofone]

Description

This will make code completion add `...` into my code. Vscode will auto show `...` in completion panel, there is no need to `substring` onCompletion

SEO: truncate

here's a repro:

from typing import Literal


type Foo = Literal["aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"]

foo: Foo = '' # completion here

thanks for finding the code
