Is the transition hooks' call context right?

[TerenceZ]

If I apply a transition on a component A who isn't fragment, the transition hooks (resolved from B)' call contexts point to A, not the component B. For example following, I can't get the props I wanted to animate, because the this is pointing to inner instance, not the comp instance.

Have I missed something? Because I don't know why the context should be bound to the inner, and if I really want to access inner's props, I can access it through the $refs.inner...

<template>
<div>
  <inner transition="tran" v-show="visible"></inner>
</div>
<template>
<script>
export default {
  name: "comp",
  transitions: {
    tran: {
      enter(el, done) {
        // I want to access some props on `comp`, but the `this` points to `inner` instance:(
      }
    }
  }
}
</script>
