Conditionally rendered teleported component does not unmount

[greeeg]

Version

3.0.0-rc.5

Reproduction link

https://codesandbox.io/s/cool-shape-018sv?file=/src/index.js

Steps to reproduce

• Open the modal by clicking the "Open modal" button
• Edit the email input field
• Try to close the modal using the "Close modal" button

What is expected?

The modal is successfully closed by sending the event to the parent component which updates its state and unmount the modal.

What is actually happening?

When editing the email input field and then trying to close the modal, Vue throws an error indicating that an unhandled error happened during execution of scheduler flush.

---

The issue is only visible when using the teleport component.

It seems related to an issue posted earlier I didn't see #1813. Feel free to close this one if needed.
