Keep compartmentalized extensions in sync with external state. If the state that determines the value of a compartment necessarily lives outside the CodeMirror EditorState (say, an app-wide theme picker), this hook can be used to keep it in sync with the EditorState. To avoid state tearing, this hook calls the `setEditorState` argument in the render phase. This means that it _must_ be used in the component that owns the EditorState. If your EditorState lives in a global state manager, you should not use this hook.

Keep compartmentalized extensions in sync with external state.
If the state that determines the value of a compartment necessarily lives outside the CodeMirror EditorState (say, an app-wide theme picker), this hook can be used to keep it in sync with the EditorState.
To avoid state tearing, this hook calls the
setEditorStateargument in the render phase. This means that it must be used in the component that owns the EditorState. If your EditorState lives in a global state manager, you should not use this hook.
