Description

NetworkBehaviourUpdater.NetworkBehaviourUpdate() update every network variables for every connected clients. Inside of NetworkBehaviour.VariableUpdate() calls NetworkBehaviour.PreNetworkVariableWrite() and it clear list variable NetworkVariableIndexesToReset. But last client(in networkManager.ConnectedClientsList)'s variable is changed which has NetworkVariableWritePermission.Owner, at the last of update loop, it clears NetworkVariableIndexesToReset and ignore write because this client has write permission of that variable. So at the end of update loop NetworkVariableIndexesToReset is cleared. And called NetworkBehaviour.PostNetworkVariableWrite => do nothing. Server side : this NetworkVariable remains dirtyflag is true. and calling WriteDelta() at every Update.

Reproduce Steps

1. Host client A(client id: 0), Clients B(client id:1), C(client id:2) and they have NetworkVariable with NetworkVariableWritePermission.Owner.
2. Update C's variable.
3. Server start calling WriteDelta() of C's NetworkVariable every tick.
4. B received ReadDelta of C's NetworkVariable every tick.
