Croll overlap - How to handle those?

[Vadorequest]

Depending on the size of the screen, my conditions overlap each other and if makes a mess of my breadcrumb.

I wonder if we could get a direction in addition of the existing options. So we can know if the scroll is going towards the bottom or the upper side of the page.

Here is a short video that shows the bug in action: https://youtu.be/PzQxfHRzOyY

The point of a direction argument would help resolve conflicts between different rules, in the onProgress function.
