What version of Bun is running?

1.2.18

What platform is your computer?

Darwin 24.5.0 x86_64 i386

What steps can reproduce the bug?

Hi,

I would like to report a difference in Bun's behavior/output when Bun handles importing Node/npm code. The difference can be noticed when you run the following snippet as it is, and when you comment line 1 and run it again. I suspect it is connected to how Bun handles Node/npm code.

const fs = require("fs"); //comment this and see

function g() {
    console.log(Object.getOwnPropertyNames(this))
    return typeof this;
}

g();

Regards,

AH
