Root component seems to not being unmounted when closing the editor [iOS only]

[fluiddot]

Describe the bug
While working on wordpress-mobile/WordPress-iOS#20657, I noticed that the React Native root component is not being unmounted or at least the function componentWillUnmount is not being called. I understand that the component is destroyed/deallocated at some point after closing the editor, but I wanted to reflect this unexpected behavior in a GitHub issue for reference.

To Reproduce

1. Apply the following patch:

diff --git forkSrcPrefix/packages/react-native-editor/src/index.js forkDstPrefix/packages/react-native-editor/src/index.js
index adb33b8943bdeb9e432d1bb85ee100c1363ea7fa..ca3f58fb5407b9baf27a7aa6b35edbbf8374de2e 100644

+++ forkDstPrefix/packages/react-native-editor/src/index.js

 		componentDidMount() {
 			// Dispatch post-render hooks.
+			console.log( 'root tag mounted' );
 			doAction( 'native.render', this.filteredProps );
 		}
 
+		componentWillUnmount() {
+			console.log( 'root tag unmounted' );
+		}
+
 		render() {
 			return cloneElement( this.editorComponent, this.filteredProps );
 		}

2. Open the editor.
3. Observe in the console that the message root tag mounted is printed.
4. Close the editor.
5. Observe in the console that the message root tag unmounted is NOT printed.

Expected behavior
The componentWillUnmount function should be called when closing the editor.
