in Kafka, with Idempotence producer, is there a possibility of gaps in a topic partition?

Assume a KAFKA PRODUCER application (C++, librdkafka, with enable.idempotence=true) which produce msgs 1,2,3,4 and 5 in order for a single topic partition.
Is there a possiblity of kafka writing (i.e. for a Consumer when reading), these msgs with a gap ?
e.g. is there a possiblity of kafka writing 1,2,5 (i.e. when consumer reads, they get 1,2,5) – 3 and 4 missing.
