I think also need to catch errors.New("tx too big") error

if if !pool.chainconfig.Scroll.IsValidBlockSize(tx.Size()) { can catch all cases that "one tx cannot fit into a block", then we don't need to catch errors.New("tx too big") error for the moment, because these txs can at least fit into an empty block.

if you don't deal with the error, the exist error tx will stay in the txpool forever

A reboot will get rid of those txns, it is fine.

It might be nice to add a test to avoid a regression in the future

makes sense. I also believe reboot and repropagation (then rejection by tx pool) can resolve this.
