Passing component to nested slots gives TypeError: Cannot read property 'parentNode' of null · Issue #3548 · vuejs/core · GitHub

3.0.11

Click the rendered dropdown button with the component included in the slot "popoverContent". Commenting out the component and refreshing gives expected behavior, toggling the popover with "hello".

Expect to be able to render arbitrary content, including other components, in the nested slots.

When a component is included in the nested slot content, an error is thrown: "TypeError: Cannot read property 'parentNode' of null."

This error goes away and normal behavior is seen when only text is included in the slot.

I am implementing a custom toolbar with buttons that can be passed content to be displayed in a popover. The component has a slot "popoverContent". then includes a component with a slot "content". The content is passed through those two slots. Including any other component in that slot content produces this error.
