Same fix as for checkbox (commit [1]) and select (commit [2]). The radio buttons were forgotten. Check commit [1] for in-depth explanation, but this is basically because since the qweb engine conversion to OWL (done at [3]), it would toggle the internal `checked` value and not the `checked` attribute anymore.
