crates/blockifier/src/state/cached_state.rs line 623 at r3 (raw file):

    pub fn update_sequencer_key_in_storage(&mut self, tx_context: &TransactionContext) {
        let seqencer_address = tx_context.block_context.block_info.sequencer_address;
        let seqencer_is_sender = seqencer_address == tx_context.tx_info.sender_address();

Suggestion:

        let sequencer_address = tx_context.block_context.block_info.sequencer_address;
        let sequencer_is_sender = sequencer_address == tx_context.tx_info.sender_address();
