React warning, when using the editor

[Manage0]

Hi!

I have the following code:

<Editor
editorState={editorStateEN}
onEditorStateChange={(e) => { setEditorStateEN(e) }}
/>

And this warning message:
Warning: Can't call setState on a component that is not yet mounted. This is a no-op, but it might indicate a bug in your application. Instead, assign to this.state directly or define a state = {}; class property with the desired state in the c component.

It appears when the component mounts. The code does not break, it is just a warning, so it isn't a high priority issue, I am just telling you, it could be interesting.

Can anyone explain why is this happening?

I am using the currently newest version 1.15.0, but it appears in 1.14.7 too.

Thank you in advance!
