Not initialize boolean property properly

[TerenceZ]

Example:

<test></test>

<script>
new Vue({
    el: "body",
    components: {
        "test": {
            props: [
                {
                    name: "prop",
                    type: Boolean
                }
            ],
            data() {
                return {
                    prop: true
                };
            }
        }
    }
});
</script>

After initialized, the test's prop is set to false, not the specified value true, who initialized in data(). I find that the compiler set the boolean value to false as default before initializing the default data).
