Summary:
When starting the surface, _propagateStageChange is called. This checks the delegate to call surface:didChangeStage: on it.
When initWithSurface:sizeMeasureMode: is called after start, then the delegate will be nil and thus not be called.
This turns it around so a delegate is present for the surface to propagate its state to.
This fixes RCTContentDidAppearNotification not getting posted otherwise.
## Changelog
[iOS] [Fixed] - Post RCTContentDidAppearNotification with new arch
Pull Request resolved: https://github.com/facebook/react-native/pull/33402
Test Plan:
I found it best to set a breakpoint in XCode to where RCTContentDidAppearNotification is being posted.
Prior to the patch that breakpoint will not be called. After applying the patch, it will be called.
