window.scrollTo with options not working on Microsoft Edge

Question

I have a strange issue which I can only replicate on Microsoft browsers (Edge and IE11 tested).

Answer 1

The "smoothscroll" polyfill supports only "smooth" option. To support all options in scrollIntoViewOptions it's better to use seamless-scroll-polyfill (https://www.npmjs.com/package/seamless-scroll-polyfill)

Worked for me.
