cannot resolve module specifier starts with special character about esbuild_deno_loader

[babie]

I added an importmap test:
https://github.com/babie/tauri-with-deno-fresh/blob/add-importmap-test/test-importmap.ts

import {
  ImportMap,
  resolveImportMap,
  resolveModuleSpecifier,
} from "https://deno.land/x/[email protected]/mod.ts";

const importMap: ImportMap = {
  imports: {
    "./foo/": "./bar/",
    "$fresh/": "https://deno.land/x/[email protected]/",
    "@preact/signals": "https://esm.sh/*@preact/[email protected]",
    "@preact/signals-core": "https://esm.sh/*@preact/[email protected]",
    "$std/": "https://deno.land/[email protected]/",
  },
};
const importMapBaseURL = new URL(import.meta.url);
const resolvedImportMap = resolveImportMap(importMap, importMapBaseURL);
console.log("resolved importmap:");
console.dir(resolvedImportMap);

const moduleSpecifiers = [
  "./foo/test.js",
  "$fresh/server.ts",
  "@preact/signals",
  "@preact/signals-core",
  "$std/dotenv/load.ts",
];
const baseURL = new URL(import.meta.url);
console.log("resolved module specifiers:");
for (const moduleSpecifier of moduleSpecifiers) {
  const resolvedModuleSpecifier = resolveModuleSpecifier(
    moduleSpecifier,
    resolvedImportMap,
    baseURL,
  );
  console.log(`${moduleSpecifier} -> ${resolvedModuleSpecifier}`);
}

but importmap module ran as expacted:

$ deno run test-importmap.ts

resolved importmap:
{
  imports: {
    "file:///Users/babie/src/github.com/babie/tauri-deno-fresh/foo/": "file:///Users/babie/src/github.com/babie/tauri-deno-fresh/bar/",
    "@preact/signals-core": "https://esm.sh/*@preact/[email protected]",
    "@preact/signals": "https://esm.sh/*@preact/[email protected]",
    "$fresh/": "https://deno.land/x/[email protected]/",
    "$std/": "https://deno.land/[email protected]/"
  },
  scopes: {}
}
resolved module specifiers:
./foo/test.js -> file:///Users/babie/src/github.com/babie/tauri-deno-fresh/bar/test.js
$fresh/server.ts -> https://deno.land/x/[email protected]/server.ts
@preact/signals -> https://esm.sh/*@preact/[email protected]
@preact/signals-core -> https://esm.sh/*@preact/[email protected]
$std/dotenv/load.ts -> https://deno.land/[email protected]/dotenv/load.ts

there might be a bug on esbuild_deno_loader.

memo:

parhaps because esbuild_deno_loader uses args.namespace(default: file) on build.onLoad() and build.onResolve() as it is.
