Describe the solution you'd like

Maybe follow the best practice, to not use second argument?

Describe alternatives you've considered

As an alternative I've only stripped the second (unsupported) parameter and this at least keeps that test functional:

const { getComputedStyle } = window;
window.getComputedStyle = (elt) => getComputedStyle(elt);
