Description
When using a computed property based on a reactive array, mutating the array with .splice() doesn't seem to trigger a re-computation, leading to stale values in the template.
Expected Behavior
The computed property should automatically update when the underlying reactive array is mutated (e.g., with .splice() or direct index mutation), and the DOM should reflect this change.
Actual Behavior
Even after calling .splice() on the reactive array, the computed property is not re-evaluated and the template does not update unless a workaround (like reassigning the array) is used.
