Performance optimization with react when css object doesn't change

Feature/Performance improvement

What is the current behavior?

I am re-loading data into a panel and although that data is only relevant to one question, I am seeing all questions reload. When I inspect this in the react profiling tool, I see that the component thinks the css prop has changed, because it is not doing a deep comparison.

What is the expected behavior?

I would like to improve performance by checking that the css object has not actually changed through a deep comparison on shouldcomponentupdate.
