happy-dom window eval "is not a function" in Bun

[canadaduane]

What version of Bun is running?

1.1.43+76800b049

What platform is your computer?

Linux 6.9.3-76060903-generic x86_64 x86_64

What steps can reproduce the bug?

When asking happy-dom to eval a script, it fails to do so.

It fails with the following error: TypeError: this[PropertySymbol.window].eval is not a function:

I've written a reproducible example of the error at https://github.com/canadaduane/happy-dom-eval-issue

What is the expected behavior?

Bun should evaluate the script module offered in the happy-dom script tag. When running with node 23.2.0, the repro prints "hello world" as expected.

What do you see instead?

$ bun happy-test.js

275 |                 browserSettings.errorCapture !== BrowserErrorCaptureEnum.tryAndCatch) {

277 |             }

minimum reproduction:

import * as vm from 'node:vm';

class A {
    globalThis = this;
    constructor() {
        vm.createContext(this);
        new vm.Script('this.eval = globalThis.eval').runInContext(this);
    }
}

console.log(new A());
expect(new A().eval).toBe(eval);
