Currently key attribute is silently skipped, shouldn't this be set as attribute or property or at least in dataSet?

Nope, it should not:

Keys serve as a hint to React but they don’t get passed to your components. If you need the same value in your component, pass it explicitly as a prop with a different name

_source

This is not react and key have to be accessible somehow to be any useful, for example to use with morphdom. Otherwise should be removed from types.

jsx-dom strikes to emulate React’s API and behavior as much as possible, that’s why key is stripped away.

And another thing to change in patch-package...

Completely removing key is wasteful, since it could be used with packages like morphdom, especially when somebody consciously adds key attribute to the code. Of course I could use id or class or dataset, but 1. this is inconvenient 2. some tools like eslint have special rules for key. Keeping key as at least dataset['jsxKey'] or data-jsx-key would make way more sense than silently throwing it away. Same goes for capture variants of events - PR is waiting for feedback.

However some additional features are present, this could be one of them.

Edit: In #17 you already accepted change to divert from react-like implementation, also for morphdom use case.
