This looks great! A few changes:

1. Can we sync with the latest next? There are some testing changes that I would like for this to run.
2. Can we see if we can do without the typecasting when emitting ionInput?

Branch is now rebased against next. Typecasting can be removed in a future task (captured), once the Stencil public runtime types are updated/released.
