Description

Currently we provide a value (defaultValue which is a stringified version of the content state). Each time content changes it returns a content states in onChange and if you save it in a state which passes as defaultValue you will have to stringify again.

Suggestion

Allow contentState object as defaultValue or perhaps a separate props contentState

<RichTextEditor
    draftEditorProps={{
        editorState,
    }}
