Steps to reproduce

• Observe the initial render result in preview, we can see for number value and boolean true, they are actuall strings

• click toggle for several times, we can see later results are correct

What is expected?

value type should be as it is

What is actually happening?

I know if I use type: Number for props, vue will transform them into number, but if it's a mixed types(or no type definition) like below, vue will not do the transform, that is useful if we want to use the props as they actually are

props: {
  value: {},
},
props: {
  value: {
    type: [Number, String, Boolean],
  }
},

In initial render, primitive values are reflected into attributes because of below code

this._resolveProps(this._def)
this._setProp(key, val, true, true)

that happens in constructor, but later in _resolveDef, attributes are used again in this._setAttr and then cause this issue
