Starknet has proposed the following alternative for vote sync.
If there is no round change. periodically rebroadcast the local votes, i.e. the one a node generates and not what it has received from other nodes.
Prevote is resent at timeout_preovote interval, precommit at timeout_precommit.

This is the solution 1. proposed in #235.

Namely, improving reliability on the votes broadcast by adopting a stubborn channel approach.

Notice that this is not able to address deadlocks produced by Byzantine behavior (equivocation) as in #576.
