Steps to reproduce

Open the link, look at the output. lengthIs0 is showing true

What is expected?

lengthIs0 should have been recomputed after the setTimeout - however, it appears after initial optimization related to the v-if statement, the hook is not being added back on conditional change.

This worked in 3.4 - and works in composition api, however, is not working for options in 3.5.7 (or 8)

What is actually happening?

Computed, is not, in fact, computed.

System Info

No response

Any additional comments?

I upgraded from 3.4 ==> 3.5.7 and a unit test broke, upon investigation, this is where I landed.
