LSP does not resolve jsr: specifiers pointing to a single workspace JSR package to itself

Version: Deno 1.41.1

// mod.ts
export function add(a: number, b: number): number {
  return a + b;
}

// deno.json
{
  "name": "@luca/add2",
  "version": "1.0.0",
  "exports": "./mod.ts",
  "imports": {
    "@luca/add2": "jsr:@luca/add2"
  }
}

// mod_test.ts
import { add } from "@luca/add2";
const x: number = add(1, 2); // 3

The CLI correctly resolves when you deno run mod_test.ts, but the LSP errors because @luca/add2 is not published to JSR.
