Having this same problem. Any progress on this? BTW: Quick solve was to downgrade the version (for anyone coming across this open issue).
@agutoli just tested, still the same error. Using Jest `"jest": "20.0.4"` and `"react": "^16.2.0"`. Also tested with the latest stable release of jest `22.3.0` and received the same `MutationObserver` error....
@agutoli sorry about the delay. Still failing:   This is the install from `2.1.2-alpha`:  I wonder if the version of `react-shadow` is a problem here? I don't know....
