One way of fixing this is to forbid sending a stateless reset unless the size of the stateless reset will be smaller than the packet that has triggered the stateless reset.

Note that endpoints are already required to send a large packet after quiescence, if they want to see stateless reset in case the server has lost state. See the following statement in [section 6.10.4](https://quicwg.org/base-drafts/draft-ietf-quic-transport.html#rfc.section.6.10.4):
> An endpoint SHOULD NOT send a stateless reset that is significantly larger than the packet it receives.
