Scroll limit broken has no effect in 2.x

Fixed scroll limit behavior.

The scroll limit was handled from the preloader to avoid loading of heavy library.
Now it moved into the main library where it is still making sense to avoid the "LCP" (largest meaningful content pain) loading slow.

Also fixed behavior for not scrollable/short pages. Recalculating the scroll limit by take the max scroll height into account.

Added to 2.x. Will be included >= 2.0.4

Thank you so much @jfeltkamp!! Great news before the new year! 🚀
So we just need to update the JS lib!
