I yarn dev the react-example project and tried connecting a color outpin to its parent's color inpin, and got an error.

Compiled with problems: × ERROR [MobX] invalid action stack. did you forget to finish an action? at die (http://localhost:3000/bundle.js:14092:11) at _endAction (http://localhost:3000/bundle.js:15128:5) at executeAction (http://localhost:3000/bundle.js:15086:5) at Output.connect (http://localhost:3000/bundle.js:15069:12) at at.commitDraftConnection (http://localhost:3000/bundle.js:72406:1679) at Be (http://localhost:3000/bundle.js:72394:83826) at at.commitDraftConnection (http://localhost:3000/bundle.js:72394:83670) at http://localhost:3000/bundle.js:72477:760 at HTMLUnknownElement.callCallback (http://localhost:3000/bundle.js:24584:14) at Object.invokeGuardedCallbackDev (http://localhost:3000/bundle.js:24633:16) ERROR [MobX] invalid action stack. did you forget to finish an action? at die (http://localhost:3000/bundle.js:14092:11) at _endAction (http://localhost:3000/bundle.js:15128:5) at executeAction (http://localhost:3000/bundle.js:15086:5) at Output.connect (http://localhost:3000/bundle.js:15069:12) at at.commitDraftConnection (http://localhost:3000/bundle.js:72406:1679) at Be (http://localhost:3000/bundle.js:72394:83826) at at.commitDraftConnection (http://localhost:3000/bundle.js:72394:83670) at http://localhost:3000/bundle.js:72477:760 at HTMLUnknownElement.callCallback (http://localhost:3000/bundle.js:24584:14) at Object.invokeGuardedCallbackDev (http://localhost:3000/bundle.js:24633:16) ERROR Maximum call stack size exceeded RangeError: Maximum call stack size exceeded at webpack_modules__.../../node_modules/rxjs/dist/cjs/internal/Subscriber.js.ConsumerObserver.next (http://localhost:3000/bundle.js:56367:17) at webpack_modules.../../node_modules/rxjs/dist/cjs/internal/Subscriber.js.Subscriber._next (http://localhost:3000/bundle.js:56331:26) at webpack_modules.../../node_modules/rxjs/dist/cjs/internal/Subscriber.js.Subscriber.next (http://localhost:3000/bundle.js:56302:18) at http://localhost:3000/bundle.js:56120:34 at Object.errorContext (http://localhost:3000/bundle.js:64334:9) at __webpack_modules.../../node_modules/rxjs/dist/cjs/internal/Subject.js.Subject.next (http://localhost:3000/bundle.js:56110:24) at webpack_modules__.../../node_modules/rxjs/dist/cjs/internal/ReplaySubject.js.ReplaySubject.next (http://localhost:3000/bundle.js:55982:31) at webpack_modules.../../node_modules/rxjs/dist/cjs/internal/Subscriber.js.ConsumerObserver.next (http://localhost:3000/bundle.js:56364:33) at __webpack_modules.../../node_modules/rxjs/dist/cjs/internal/Subscriber.js.Subscriber._next (http://localhost:3000/bundle.js:56331:26) at __webpack_modules__.../../node_modules/rxjs/dist/cjs/internal/Subscriber.js.Subscriber.next (http://localhost:3000/bundle.js:56302:18)

I want to use it to implement a flow graph without data observation, but the observable param is indispensable. That's a little awkward.
