when-visible from below

[edencorbin]

It looks like it triggers when the start of the element is in view, based on delay-percent. However, it does not have an equal trigger when the end of the element is in view. For instance if I have a large div and scroll in from the bottom I need to be nearly at the top for this to work. A workaround is to set up two divs that trigger and work with the angular responses, but am I missing something for scrolling up/from below on long divs?
