Bundler load function not called before throwing

[WilcoKruijer]

I would expect in the following case that the load function would be called before erroring out of the bundling.

It seems that the documentation of the load method agrees with this:

Override the default loading mechanism with a custom loader. This can provide a way to use "in-memory" resources instead of fetching them remotely.

// repro.ts
import { type CacheSetting, createCache, type LoadResponse } from "jsr:@deno/cache-dir";
import { bundle } from "jsr:@deno/emit";

const bundleCache = createCache({});

const load = (
  specifier: string,
  isDynamic?: boolean,
  cacheSetting?: CacheSetting,
  checksum?: string,
): Promise<LoadResponse | undefined> => {
  if (specifier === "does-not-exist") {
    return Promise.resolve({
      kind: "module",
      specifier,
      content: `export function func() { console.log("hello world"); }`,
    });
  }

  return bundleCache.load(specifier, isDynamic, cacheSetting, checksum);
};

await Deno.writeTextFile(
  "./my-thing.js",
  `
  import { func } from "does-not-exist";
  func();
  `,
);

const { code } = await bundle("./my-thing.js", {
  load,
});

console.log(code);

The code above fails with

 deno run -A repro.ts
error: Uncaught (in promise) Error: Unable to output during bundling: load_transformed failed: failed to analyze module: failed to resolve does-not-exist from file:///Users/wilco/dev/wilcofirst/packages/browser-test-runner/my-thing.js: Cannot resolve "does-not-exist" from "file:///Users/wilco/dev/wilcofirst/packages/browser-test-runner/my-thing.js".
      const ret = new Error(getStringFromWasm0(arg0, arg1));
