godot: RPCs must be echoed in child class, otherwise they don't work.

Godot version

Issue description

Currently experiencing an issue with RPCs and inheritance.

In the parent class, I have the following code:

@rpc("any_peer", "call_local")
func Sync_addImpulse(swingImpulseString : String):
	if multiplayer.get_remote_sender_id() == 0:
		rpc("Sync_addImpulse", swingImpulseString)
	else:
		var swingImpulse = JsonSingleton.parseVector2FromString(swingImpulseString)
		addImpulse(swingImpulse)

When I call Sync_addImpulse in the child class, the function is called (e.g., it forwards teh RPC). However, the RPC isn’t received.

To fix, this, I simply echoed the call in the child as follows:

@rpc("call_local", "any_peer")
func Sync_addImpulse(impulse): super.Sync_addImpulse(impulse)

Strangely, it now works as expected. It seems like maybe the rpc tag isn’t inherited by the child, but that’s just a wild guess.

Let me know if you have any questions or if I can help at all.

Steps to reproduce

• Create a parent & child class
• Create some method CallRPC() in the parent class, that echoes an RPC to itself (like the one I provided)
• Call the CallRPC() method from the child class. The parent class will run CallRPC(), but it won’t receive the self-echoed RPC.
• Then, echo the CallRPC() function in the child class. You will observe that now the RPCs are received.

Minimal reproduction project

N/A - quite trivial.
