ubuntu by default does align partitioning to 2MB boundary to be 4k drives friendly, and accommodate bootloaders that spillover the MBR (like latest grub2, if enough core modules are enabled).
Maybe specifying that this is an alignment buffer would make sense, or e.g. not showing it at all.
This is not it at all though. This is an BIOS BOOT partition for booting GPT drives in BIOS mode. I think we should still fix up how we present this to the user and avoid forcing them to create it for their systems to boot properly, but I'm not sure yet if the best thing is to hide it completely and "lie", or show it and be a little confusing (or finding some balance between the two and showing it in some very obvious way and make sure it's clear it's not to be touched).
