This is expected. It was masked previously with /etc/mtab hacks.

This is a bug, but is actually fixed in this util-linux release - you do
however need to regenerate the initrd to get the fix.

This is simply something done by systemd to ensure that /media is
writable. Some filesystems have readonly / and thus cannot have such
mountpoints added. Using tmpfs ensures that all mount points can be
created easily.

The actual partion size is pretty much irrelevant. It doesn't use that
space at all, it's just what the tmpfs driver does when it's loaded
without specifying a specific size. As the memory is just addressable,
but not allocated, there is no real need to artificially lower the size.

All the best
