Animation event failure on portait orientated desktop screen

[sawsm]

Animation behaves nominally across all devices and screen orientations. However, from a desktop monitor at 1920x1080p resolution, configured in portrait orientation ( rotated 90 degrees clockwise ) the animation fails to trigger. Moving the browser to a landscape oriented screen immediately triggers the animation event.

I can constantly reproduce the anomaly with
fadeInUp on button element - when it is the last element in single column footer row

Observed from Windows 10 using:
Firefox Developer Edition: 55.0b11 (64-bit)
Google Chrome Version 59.0.3071.115 (Official Build) (64-bit)

Thanks for reporting. basically, we are using animate.css for the animation.

To better understand and report the issue in the animate.css repo, I need to know if it's only with the "fadeInUp" animation? only on a button? any other relevant data you can provide.
