The problem is stated in the docs as well:
Handwritten Components
You don’t need to use the
@react.componentdecorator to write components that can be used in JSX. Instead you can write themakefunction with typepropsand these will always work as React components. But then you will have the issue with the component name being “make” in the React dev tools.
– Components and Props | React –
As you can see in your playground example, the first component will be named “make”, the second “Playground$WithDecorator”.

While debugging a bundled spa, I see a lot of make functions. make1, make2, …, make35.
Fortunately there is a comment with the file name above the component declaration:

But where the component is referenced - only the makeN function
