I got a jelly roll from a an online shop in a FRE. It was taped all around with packing tape too. The post office has to be shown their own rules sometimes! I know some of the clerks in my local post office get on a high horse about what they think is the rule. I have written to the post master general with pictures of what was refused and I have taken my reply right to the clerk who refused to mail the package as I had it. They see their name in the letter to the PMG and they start learning the rules as written not what they were told by other employees or bosses.
