Changing props does not update

Nobody has claimed this yet.

If you run the playground app and then edit `lib\src\Component.vue` to change the prop, e.g. rename `message` to `msg`, saving updates the UI and hides the message on the screen (as you would expect, it's no longer receiving a value for that prop). However, if you then update App.vue in the playground to use `msg` not `message`, whilst you can see HMR fires an update for `App.vue` it does not start rendering the message again. The JS console prints some warnings stating that you are passing an extraneous prop `msg` and missing the required prop `message`.

This is the case regardless of whether the component is registered via a plugin, or imported directly in App.vue.

It's easily worked around with a quick refresh - but perhaps there is a way to get it working?

Start by reproducing the prop rename workflow in the playground, using lib\src\Component.vue and the playground's App.vue, and compare direct registration with plugin registration. Trace the HMR update after App.vue changes; done means the message renders again without a refresh and the extraneous or missing prop warnings disappear.
