Test on pangoro<>pangolin. The bridge is running. But cannot find it submit headers from pangoro to pangolin. Even restart, it doesn't work. The latest submission is about 10 hours ago.

A possible reason:

If the validator is not enough, no authorities change record will be generated.

https://github.com/darwinia-network/parity-bridges-common/blob/7be2b478b49bc8e87ddfe034076e9e80e2f126f6/relays/finality/src/finality_loop.rs#L462-L463

Then, a mandatory block will not be found here.

won't fix recently, expected to no longer exist if replaced by subquery.

And if there is no new authorities change, and no mandatory block, the bridger will have to query from node for grandpa justification (depend on node settings, node will store justification every 500 blocks?)
