Recursive component inconsistent behaviour with Vue 2

[AaronCQL]

Version

3.0.0-beta.15

Reproduction link

https://github.com/AaronCQL/vue-3-recursive-component

Steps to reproduce

After cloning the repository:

$ npm install
$ npm run serve

Notice that the HelloWorld component renders from 1 to 10 without throwing any errors/warnings.

Now, build and serve the files:

$ npm run build
$ serve ./dist

Notice that the HelloWorld component only renders the first one.

What is expected?

The name option in the HelloWorld component has been deliberately left out. As documented in https://vuejs.org/v2/guide/components-edge-cases.html#Recursive-Components, recursive components should only be able to invoke themselves in their own template with the name option.

Running npm run serve with this same code on Vue 2 will only render the first HelloWorld and throw the warning: Unknown custom element: <hello-world> in the console and suggest about adding the name option.

What is actually happening?

Running npm run serve on this code with Vue 3 does not throw any warnings/errors and actually renders the HelloWorld component 1 through 10 (unlike in Vue 2). The actual built files on the other hand will only render the first HelloWorld component (similar to Vue 2).
