Vue version

3.2.47

Link to minimal reproduction

See below

Steps to reproduce

Perfectly valid code till now:

const selected = ref("")
<input v-model="selected" type="radio">

running vue-ts (or looking at the code inside VS Code) complains:

  node_modules/@vue/runtime-dom/dist/runtime-dom.d.ts:646:3
    646   checked?: Booleanish | any[] | Set<any> // for IDE v-model multi-checkbox support
          ~~~~~~~
    The expected type comes from property 'checked' which is declared here on type 'ElementAttrs<InputHTMLAttributes>'

Changing selected to an array silences the error, but an input of type "radio" output one and only one value on output. Is it a bug?

What is expected?

Continue as before without complaining

What is actually happening?
