Nested component's v-model doesn't trigger its updated lifecycle method when a parent dynamic component is updated by provide/inject

[linnea]

Version

2.5.16

Reproduction link

https://jsfiddle.net/linnea/zmkt7ajy/15/

Steps to reproduce

1. Click on the working checkbox. The v-model value updates and the "updated" lifecycle event fires a console log.
2. Click on the "busted" checkbox, which is the same markup as the working checkbox, but wrapped within a div inside the DynamicWrap component.

Notice that the checkbox appears checked, but the v-model doesn't update and the "updated" lifecycle event of the checkbox never fires.

What is expected?

The second checkbox's v-model updates correctly

What is actually happening?

No updated lifecycle event fires, the v-model is not updated.

What's happening:
The DynamicWrapper is rerendered after mount when the UnwrappedCheckbox is created inside of its default slot. UnwrappedCheckbox uses provide/inject to update the DynamicWrap component to wrap it with a 'div' instead of a 'label' element. This clones the content inside, but once the Checkbox is nested a layer deeper, it stops behaving as expected.

Sorry for the monster title and complex replication, let me know if there's anything more I can do to clarify. For context, the purpose of this DynamicWrapper is to act as a type of "FormItem" component. It wraps any element placed inside of the component (In this case a Checkbox) with a label element unless it's something like a Checkbox or Radio. We have our own Checkbox and Radio, that we'd like to tell the FormItem to unwrap the label if a Checkbox is placed inside it.

I've also tested in the beta prerelease and the issue remains.
