Getting a string "JS Bin Output" instead of undefined

[Gaya3G]

Below code logs "JS Bin Output" instead of undefined.

var name;
console.log(name);

name actually contains window.name which in the case of the output panel, the iframe actually does have a name value.

It's a long standing weird global variable, here's some backstory too: https://remysharp.com/2021/01/21/that-other-global-name
