children types not preserved

[landabaso]

Suppose:

render() {
  const i = 0;
  return <Component>{i}</Component>
}

Then in Component typeof this.props.children === 'string'.
In React the type is still a Number.
I can of course parse the result but I guess this is something that has to be fixed?

Thanks for this project!

That's an interesting one. Preact normalizes types, but I guess maybe we should be skipping that normalization for components, instead only applying it to element VNodes.

Well, that normalization breaks compatibility I guess...
In my App it throws because I'm already assuming I get a Number.
What is the underlying reason for that normalization?

It simplifies the diff and avoids passing too many types through the algorithm in order to keep IC size down. That said, it's only number and string now, booleans are always removed.
