Summary: I noticed some strange behaviour in a collection view I was testing that was using `IGListCollectionView` and `IGListCollectionViewLayout`. Even if I called `invalidateLayout` on it, the cells wouldn't resize and would sometimes end up overflowing outside the collection view's bound. I eventually managed to trace this back to `IGListCollectionViewLayout` that uses a `_minimumInvalidatedSection` flag to track when list content has changed before it starts calling the sizing logic of each section controller. While `invalidateLayoutWithContext:(IGListCollectionViewLayoutInvalidationContext *)context` was correctly setting this flag, `invalidateLayout` wasn't subclassed, and so this call was basically always falling through. This diff configures `invalidateLayout` to set this flag, so when this method is called, it will correctly perform a new cell sizing pass.
