No, the situation described upthread is about a deadlock error, not a typo. In MySQL, syntax errors throw a statement-level error but it does not affect the transaction state in any way. If you were in a transaction, you're still in a transaction after a typo.

With deadlocks in MySQL, the error you receive is "Deadlock found when trying to get lock; try restarting transaction" i.e. it specifically tells you the transaction needs to start over in that situation.

In programmatic contexts, transactions are typically represented by an object/struct type, and a correctly-implemented database driver for MySQL handles this properly and invalidates the transaction object as appropriate if the error dictates it. So this isn't really even a common foot-gun in practical terms.
