Same here.

the cause is that the input element's input event cannot be handled by v-model in 2.5.0, so the parent radio group will never $emit

A thing to note:
If you import redio button directly from source (with webpack), that said, use import ElRadioButton from 'element-ui/packages/radio-button' and use it in your code, the component will work again.
So this bug seems to be a regression on vue's side

seems similar cause for #7474

posted an issue in vue vuejs/vue#6803

it is to be fixed in vue's next patch version

@KagamiChan Thanks for boiling it down.

Upgrading Vue to 2.5.2 fixes this: https://jsfiddle.net/pgn7gyu9/1/
