Problem Description

For phetsims/qa#488. In https://phet-dev.colorado.edu/html/energy-forms-and-changes/1.2.0-dev.12/phet-io/, I'm seeing a huge slowdown in the state wrapper on my MacBook Air. When I use the profiler query parameter, I can get the FPS down to 2 pretty quickly. The blocks like to float on their own for a few seconds. It's pretty unusable.
