There is no need to use startsWith.

Vue components may not be at the top level.
export default {
components: {
// @vue/component
MyComponent: {
data() {
return {
bar: this.baz
}
},
computed: {
baz() {}
}
}
},

I've found an issue with duplicate reports when the chain is deep. Perhaps checking the parent is a problem.
<script>
export default {
data() {
return {
a: this.test.foo.bar.baz,
}
},
computed: {
test() {
return {}
},
}
}
</script>

Why is there a console.assert call here?
