Steps to reproduce

Open vue playground then open devtools console and change prod\dev mode

What is expected?

The same behavior is expected in prod and dev mode. Reactive const will be filled in both cases

What is actually happening?

The Reactive constant is filled in dev mode, but always empty in prod

The production behaviour is correct as the template ref gets a new array reassigned - and const variables are not re-assignable.

However we should look into how to warn about this in dev mode
