Description
Currently we only rerender when the thumb changes but the list of thumbs my not be ready. This allows us to also rerender when the list changes length.
I have tested the rerenders in my local environment in React 19 it was 4 before the change and is 4 after the change, in Preact it is now 3 rerenders with the last rerender being the only time the items array contains anything.
