JS `createGraph` modifies objects returned by `load`

[0f-0b]

import { createCache } from "jsr:@deno/cache-dir@0.8.0";
import { createGraph } from "jsr:@deno/graph@0.69.7";

const { load } = createCache();
{
  // the object returned by `load` is modified,
  await createGraph("https://examples.deno.land/hello-world.ts", { load });
}
{
  // which can lead to unexpected behavior elsewhere.
  const res = await load("https://examples.deno.land/hello-world.ts");
  if (res?.kind === "module") {
    const content = res.content;
    // this should print `true` but actually prints `false`.
    console.log(typeof content === "string" || ArrayBuffer.isView(content));
  }
}
