Node incompatibility: TypeError: fetch() URL is invalid

[pubkey]

What version of Bun is running?

1.0.2+37edd5a6e389265738e89265bcbdf2999cb81a49

What platform is your computer?

Linux 6.2.0-32-generic x86_64 x86_64

What steps can reproduce the bug?

1. Create a test.js file with the following content:

async function run() {
    const myBlob = new Blob(['foobar'], {
        type: 'text/plain'
    });
    const fetchUrl = URL.createObjectURL(myBlob);
    const arrayBuffer = await fetch(fetchUrl).then(res => res.arrayBuffer());
    console.dir(arrayBuffer);
}
run();

2. run the file with bun test.js

What is the expected behavior?

It should run and transfrom the blob object into an array buffer.
In node.js it works and logs an ArrayBuffer Object.

What do you see instead?

1 | async function run() {
2 |     const myBlob = new Blob(['foobar'], {
3 |         type: 'text/plain'
4 |     });
5 |     const fetchUrl = URL.createObjectURL(myBlob);
6 |     const arrayBuffer = await fetch(fetchUrl).then(res => res.arrayBuffer());
                                  ^
TypeError: fetch() URL is invalid
 code: "ERR_INVALID_ARG_VALUE"

URL.createObjectURL is not implemented yet

@Jarred-Sumner Thank you, I didnt know that. But shouldn't URL.createObjectURL() throw instead of the later fetch() call?
