Follow up functional refs

[JoviDeCroock]

• Check if updating to the latest Preact version resolves the issue

Describe the bug

As a follow up to #3695 and #3696 - in the same reproduction if we replace the ref with a function we are calling it in the wrong order. We first call it with the div and then with the unmounted null.

To Reproduce

I have already added a test which shows the issue

Expected behavior

We expect the unmounted element to cleanup the ref and then the refto be called with the new element.
