Client's framerate impacts replication rate of his pawn to other clients

Steps to Reproduce
Hello,

We are using standard CharacterMovementComponent and we noticed that when client has very low framerate (such as 5FPS), this affects the frequency of ReplicatedMovement of his proxy to other clients.

With server-authoritative movement dedicated server is expected to replicate client’s proxy at constant rate, regardless of client’s input replication rate, but this is not what seems to be happening.

Could you elaborate on this please?
