Unexpected recursion when component's filename matches subcomponent's alias

Version

3.0.7

Reproduction link

https://codesandbox.io/s/bold-violet-1t891

Steps to reproduce

(quasar not required to reproduce the issue, but it was the fastest way to get all the right dependencies in one place)

• Open /privacy route (/#/privacy), blank page shows
• Open /fixed route (/#/fixed), Privacy Policy is displayed

What is expected?

Privacy Policy displayed in both cases

What is actually happening?

For /privacy route, console will show "Unhandled error during execution of scheduler flush."

  at <PrivacyPolicy> 
  at <PrivacyPolicy> 
  at <PrivacyPolicy> 
  at <PrivacyPolicy onVnodeUnmounted=fn<onVnodeUnmounted> ref=Ref< undefined > > 
  at <RouterView> 
  at <QPageContainer> 
  at <QLayout view="hHh lpR fFf" > 
  at <MainLayout onVnodeUnmounted=fn<onVnodeUnmounted> ref=Ref< undefined > > 
  at <RouterView> 
  at <App>

Basically, there is a conflict between multiple components having the same alias. This happens in dev mode and in production mode. There is no actual conflict, but it seems that somehow the names are being globally registered without "scoping" them to the component that creates the alias.

This issue was also reported to Quasar at quasarframework/quasar#8672

After trying Quasar@v2 beta, which uses Vue 3, privacy policy page stopped opening.

The use case here is that there is a shared component that contains privacy policy text, which can be displayed in a popup dialog and also as a standalone page.

This has a simple workaround: changing the alias of the subcomponent that is causing the problem.

For example, instead of having:

pages/PrivacyPolicy.vue

<template>
  <PrivacyPolicy />
</template>

You can have:

pages/PrivacyPolicy.vue

<template>
  <PrivacyPolicyContents />
</template>

Where PrivacyPolicyContents is just an alternative name for PrivacyPolicy defined in components of pages/PrivacyPolicy.
