Summary

Bug Fix

The ElectrumSyncClient was incorrectly treating mempool entries (height=0 or -1) from blockchain.scripthash.get_history as confirmed transactions. This caused get_merkle to fail since it cannot prove block inclusion for unconfirmed transactions, breaking sync for 0-conf channel funding transactions.

Summary
Bug Fix
The ElectrumSyncClient was incorrectly treating mempool entries (height=0 or -1) from blockchain.scripthash.get_history as confirmed transactions. This caused get_merkle to fail since it cannot prove block inclusion for unconfirmed transactions, breaking sync for 0-conf channel funding transactions.
