Extended array methods are called with unexpected values

[scottbedard]

Vue version

3.5.0-beta.1

Link to minimal reproduction

3.4.37 → 3.5.0-beta.1

Steps to reproduce

1. Create a class that extends Array
2. Use super to augment an array method

What is expected?

The extended method should be called with the provided parameter, and be able to forward that parameter to the parent method.

What is actually happening?

The extended method receives a function, regardless of what is provided by the caller.

Any additional comments?

I suspect this is related to the optimized array tracking, but have not isolated the exact cause yet.

Update: It looks like the issue lies here, our reactivity logic depends on these signatures matching the native array.
