Summary: Originally, we thought that skipping the measurement of views that were hidden would be a nice optimiatzion. Upon further review, we saw that according to Apple's `UIView` documentation: > A hidden view disappears from its window and does not receive input events. It remains in its superview’s list of subviews, however, and participates in autoresizing as usual. So, to keep parity with common iOS layout APIs, we are going to size and layout views, even if they are hidden.
