Steps to reproduce

1. open and clear the browser console
2. toggle the checkbox
3. check the console for warnings

What is expected?

no warning should be printed to the console

What is actually happening?

Using useTemplateRef in a vapor component will trigger a warning each time the ref's value is updated (when the refed element is unmounted via v-if for example).

sample warning :

[Vue warn] Set operation on key "value" failed: target is readonly. 
Object { subs: {…}, subsTail: {…}, flags: 17, __v_isRef: true, __v_isShallow: true, _rawValue: h1, _oldValue: null, _value: h1, _wrap: undefined }
