Adding active class to in-page nav using IntersectionObserver not working on tall elements
I am building a sidebar nav for a page with a lot of content in it, which scrolls to the associated section when clicked. I would like to also add a class to the currently visible section as you scroll down the page using IntersectionObserver. I have it partially working, but only when the element in question is short enough to fit entirely within the currently viewed portion of the page. If the element is taller than the page, it never triggers the intersecting. I have tried playing around with the rootMargin and threshold values but I am at a loss.
Create a WeakSet of all elements whose layout overflows documentElement
I want to create a WeakSet of all elements that are not 100% contained within the css layout bounds of the document root (<html> tag). I need to it to update in real time and not have a huge hit on browser performance.
Threshold seems to break my website, IntersectionObserver not working as intended
Recently I’ve tried to follow a youtube tutorial on scroll animations using IntersectionObserver, I followed step by step but it seems when min-weight is set to 100vh, 2 sections load in at the same time, not allowing the 2nd one to ever change.
Cannot understand how to build this scrollBar using Intersection observer api

ClearTimeout through intersectionObserver
I have the following code which loads the next project in portfolio based on an intersectionObserver result being true. If however the user scrolls out so that intersectionObserver returns false I want to stop the redirection. This is not happeneing and the page simply reloads after 5 seconds.
