How to handle watching of a reactive/non-reactive value as short as possible?

I have a list dropdown component that accepts items props which could be a reactive or non-reactive object/array.
So I watch it to react when the items change. But when I provide a static non-reactive array/object it issues warning that non-reactive value is provided for watch(). Yes, I don't care watching a non-reactive value.

solve, there's isReactive() utility
