maybe minor fix to dispatch/backend_fallback_test.cpp? (#42990)
Summary:
I think you want to push rewrapped `rets`, not `args`, back to the stack.
Doesn't matter for test purposes because tests only check if/when fallbacks were called, they don't check outputs for correctness. But it avoids reader confusion.
