Animate: Improve rendering for Safari (iOS)
Animate: Improve rendering for Safari (iOS)

This update removes the `visibility` CSS prop from the `Animate` lifecycle
styles. After some investigating/testing, I've noticed that this is somehow
causing render issues in iOS Safari (for certain render cases).

Elements would stay invisible, unless a repaint/re-render is forced.

By removing this CSS prop, we avoid potential visibility render issues
all together!
