Should these lines be reversed?

Suggested change

	const { componentName, ..._ctx } = context;
	const ctx = _ctx.__experimental?.combinedProps || _ctx;
	const ctx = _ctx.__experimental?.combinedProps || _ctx;
	const { componentName, ..._ctx } = context;

[alexcarpenter]

I don't think so, componentName only lives on the SignInCtx so we pull that off from the original context and the use the rest of the props as the context values below based on the usage of combinedProps.

Ahh I missed the _ 😅
