The desired behavior in this scenario is not to fetch historic logs, just stream any new logs.

Just looking through the relevant geth docs, toBlock and fromBlock are not even valid parameters for this method in any context so it's very confusing as to why they are being passed there in the first place.

I created a simple test app that uses the go-ethereum library to listen for events from the Wormhole core contract without needing to run the Wormhole guardian. It could be used to verify this fix. See the PR description for how to use it.
wormhole-foundation/wormhole#4214

Reminder: The desired behavior is that only new events are streamed, not historic ones.
