Critical Severity Vulnerability in intersection-observer

[salzpate]

We actually want to use mdxeditor, which uses @react-hook/intersection-observer.

However, we have now been informed that the intersection-observer contained therein is highly vulnerable.

Since the intersection observer is a polyfill and has not been developed further since 2022, I wanted to ask if you could offer a new version without this polyfill or to replace it with another, see below.

It should now be usable by all modern browsers even without polyfill.
