When switching a class on a parent element no resize happens.

**Describe the bug**
When you switch a class on a parent element using one that changes size.

**To Reproduce**
Steps to reproduce the behavior:

Make it so that a class gets added that changes the size of a parent element.

**Expected behavior**
A resize should happen as the parent div is no longer the correct size.

No file, test, or entry point is identified in the issue. Start by reproducing the case in the React masonry layout where a parent class changes its size, then trace the resize behavior; done means the layout responds with a resize when the parent changes size.
