bincode::encode_to_vec is incompatible with bincode::serde::encode_to_vec in standard configuration

[JanBeh]

Using version 2.0.0-rc.2, the following code:

fn main() {
    let array: [u8; 3] = [11, 12, 13];
    let stdcfg = bincode::config::standard();
    assert_eq!(
        bincode::encode_to_vec(&array, stdcfg).unwrap(),
        bincode::serde::encode_to_vec(&array, stdcfg).unwrap(),
    );
}

Fails with:

thread 'main' panicked at 'assertion failed: `(left == right)`
  left: `[3, 11, 12, 13]`,
 right: `[11, 12, 13]`', src/main.rs:6:5

This means bincode::encode_to_vec isn't compatible with bincode::serde::encode_to_vec. This is highly surprising.

That definitely seems like a bug, thanks for reporting
