Single-char-prefix snippet suggestion is not case sensitive

Almost same as issue 8070, in which the reported bug has been fixed. However, if the snippet prefix is a single char, suggestion remains case insensitive.

For example, if I define a Result snippet with prefix Re and return snippet with prefix re, while typing re, return will be the first suggestion. But if the prefix is R and r respectively, Result will be on top while typing r.

1. Add the following two snippets to global.code-snippets

"Return": {
	"prefix": [
		"r",
	],
	"body": [
		"return "
	],
	"description": "Return"
},
"Result": {
	"prefix": [
		"R"
	],
	"body": [
		"Result<$0>"
	],
	"description": "Result"
},

2. Type r in vs code

expected: Return is the first snippet suggestion
observed: Result is the first snippet suggestion

Thanks for your attention!

Thanks for updating/clarifying. Yes, match-scoring isn't case-sensitive towards lower-case characters, only towards upper-case characters. The logic is that lower-case characters are "the default", e.g you don't need to press another extra characters and that usually lower-case matches inside suggestions are worth less. I am not sure that we can improve this. What might help you is the "editor.tabCompletion": "on" setting - with that you can keep pressing Tab to cycle through suggestions after accepting

As issue 8070 appears, I thought snippet selections are case sensitive by design. If it is somewhat complicated match-scoring algorithm, I think I can bear with an extra tab for return .

For in fact Result<$0> is only defined for a few languages (e.g. "scope": "rust"), while return for all languages, I need an extra tab only for those languages that defined Result<$0> if I want return . It will sure be a bit annoying. Or maybe I should change the prefix to re.
