This polyfill uses a basic fallback for the document.scrollingElement property, using document.documentElement

Also, to overcome its absence if you are executing this polyfill through jsdom
, you could place this in your setup:
document.scrollingElement = document.documentElement
More context about this property can be found in:
Dev and testing
To check this polyfill you can do:
npm run dev
to launch a small page that will check browser/polyfill behaviour.
