It doesn't seem like there should be any side effects to this change since it is aligning the behavior when on_change is and is not provided

Needs regression tests and fixes for failing tests

After some additional thought, I'm going to close this. This PR tricks ReactJS into thinking everything is a controlled input, which negates some safety/guardrails that exist in the React client.

The more healthy solution is to verbosely communicate to the developer that they are utilizing an uncontrolled input when ReactPy is in debug mode:
