Setting the root-object to null in the editor results in an error

[thetruthger]

Describe the bug
Setting the root-object to null in the editor results in an error which logs:

index.esm.js:1 
 Uncaught 
TypeError: Cannot convert undefined or null to object
    at Function.keys (<anonymous>)
    at ge (index.esm.js:1:57689)
    at gi (react-dom.production.min.js:160:137)
    at xs (react-dom.production.min.js:196:258)
    at Sl (react-dom.production.min.js:291:88)
    at bu (react-dom.production.min.js:279:389)
    at vu (react-dom.production.min.js:279:320)
    at gu (react-dom.production.min.js:279:180)
    at au (react-dom.production.min.js:270:88)
    at lu (react-dom.production.min.js:272:300)

Expected behavior
The expected behavior would be to either allow the root element to be null because null is still valid JSON, or at least set it back to what it was before without breaking. :)

Screenshots

Online demo
The error occurs also in the public online demo of this tool.
