index out of bounds: the len is 2 but the index is 2

Describe the bug

thread 'main' panicked at C:\Users\PC\.cargo\git\checkouts\boa-a4b8a5f0b6a5c7b3\25705ef\core\engine\src\environments\runtime\mod.rs:652:57:
index out of bounds: the len is 2 but the index is 2
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
error: process didn't exit successfully: `C:\dev\ike\ike\target\debug\ike.exe run` (exit code: 1)

const headers = new Headers([
  ['Content-Type', ['application/json', 'dwa']]
])

console.log(headers.get("Content-Type"))

headers.get panics. It's caused by getArgument which normally works.

For example something like this works:

const atob = (data) => {
    const argument = getArgument(data, "data", "atob");
    const string = toString(argument);

    try {
        return atob_ex(string);
    } catch (error) {
        throw new Error(`atob: Failed to decode base64 string: ${error}`);
    }
};

Expected behavior
To work.

Build environment (please complete the following information):

• OS: Windows 11
• Rustc version: rustc 1.82.0-nightly (41dd149fd 2024-08-11)

Can you share a bit more info about your setup? I see that the gist uses a @std namespace on imports, and the issue doesn't mention how those are implemented.
