In my understanding the problem is with cfile.pd and wtap_seek_read() in
packet_list_store.c:packet_list_dissect_and_cache_record(), it clobbers the
data source for the first tab bytes view.
Either 1) we use a different buffer or 2) we don't update the byte view if it's
already displayed.
1) is easier to do.
2) is better but it needs a change in the logic for highlighting selected
bytes.
Note:
It's not the only case triggering this bug.
