I found a small bug on the latest version of the package. Whenever you write the hidden attribute on any component, with a value other than a string, i.e. hidden={value}, it automatically hides the attribute on the editor.
<Component hidden={true} />
becomes:
<Component />
It really doesn't matter the value of the hidden attribute, as long as the attribute is 'hidden'.
