Summary: ## Changes in this pull request Issue fixed: https://github.com/Instagram/IGListKit/issues/1275 This PR is straintforward solution as mentioned in https://github.com/Instagram/IGListKit/issues/1275. When I finished it, I realized that it is not a problem in `IGListCollectionViewLayout Partial Optimization` and `IGListBindingSectionController` deserved it. Maybe `IGListCollectionViewLayout` is rarely used because of great builtin UICollectionViewFlowLayout or cells in section rarely need changing their sizes in practices. Despite it is not `IGListCollectionViewLayout`'s fault, I think it can be more optimized against `invalidateLayoutWithContext`. I would like to make an another PR to optimize it. Due to this PR just giving a proposed solution, it lacks of adding tests and changing log. When this solution is accepted, I would like to complete these todos. ### Checklist - [x] All tests pass.
