Suspense doesn't call unmounted hook

[jods4]

Version

3.0.0-beta.4

Reproduction link

https://jsfiddle.net/L8pj7kco/8/

Steps to reproduce

Look at the console.
Component my-comp logs mounted and unmounted hooks.
When using a simple v-if (use the checkbox), it works as expect.
When the component is part of a Suspense #fallback (use button to complete), unmounted hook is never called.

What is expected?

Unmounted should be called when suspense resolves.

What is actually happening?

Unmounted is never called.
