According to the reproduction in #12427, the issue likely lies within toRef. If source is an array and the key is a number, the key should be converted to a string. However, modifying getDepFromRective broadens the impact scope. Additionally, getDepFromReactive is not a public API, and the test case should ideally use public APIs.

However, modifying getDepFromRective broadens the impact scope. Additionally, getDepFromReactive is not a public API, and the test case should ideally use public APIs.

But for getDepFromReactive, it should indeed exhibit such behavior, as it needs to handle this case for all reactive arrays.
