Bun.file().slice().arrayBuffer() returns an ArrayBuffer of wrong size

[gyf304]

What version of Bun is running?

1.1.17

What platform is your computer?

Darwin 23.1.0 arm64 arm

What steps can reproduce the bug?

const arrayBuffer = new ArrayBuffer(1000);
const blob = new Blob([arrayBuffer]);

await Bun.write("test.bin", arrayBuffer);
const file = Bun.file("test.bin");

const blobSlice = await blob.slice(0, 100).arrayBuffer();
const fileSlice = await file.slice(0, 100).arrayBuffer();

console.log(blobSlice.byteLength, fileSlice.byteLength);
// expected: 100 100
// actual: 100 1000

What is the expected behavior?

Thanks for reporting this! This is likely a duplicate of #8215, so we'll track the work there.
