Should intellisense suggest block scoped values before they are declared?

Currently intellisense suggests every block scoped declaration in scope, even if the suggestion is located within the TDZ. When accepting that suggestion, TypeScript issue an `used before its declaration` error: ```ts new /**/; // suggests 'Clazz', which results in an error class Clazz {} function test( foo = /**/, // suggests `foo`, `bar` and `baz`, all of them result in an error bar = /**/, // suggests `bar` and `baz`, both result in an error ) { let baz = 1; } ``` Should intellisense filter out suggestions that would result in an error? If so, it should probably use the same condition as the checker. Related: #28472 #28471
