Vue completion items contain hyphen("-") or start with at("@") can not be matched properly.

Make sure you have done the following

• I have updated to the latest version of blink.cmp
• I have read the README

Bug Description

I tried to modify

  exclude_from_prefix_regex = '[\\-]',

into

  exclude_from_prefix_regex = '',

but it breaks my completion, failing to sort the most relevant item first.
If I restores the config to the default one, items started with @ can not be sorted properly as well, and when I type the hypen("-"), all completions are gone.

Relevant configuration

return {
	"saghen/blink.cmp",
	-- optional: provides snippets for the snippet source
	dependencies = "rafamadriz/friendly-snippets",
	-- event = { "InsertEnter", "CmdlineEnter" },

	version = "*",
