GParted disables the 64-bit feature if the partition is small enough not
to need it (< 16 TiB).  This was done in 2016 because at the time
multiple boot loaders (Grub 2 and Syslinux) didn't understand 64-bit
ext4 file systems and couldn't boot from them.
* Bug 766910 - Multiple boot loaders don't work on 64bit EXT4 file systems
  https://bugzilla.gnome.org/show_bug.cgi?id=766910
* Only enable ext4 64bit feature when required (#766910)
  https://gitlab.gnome.org/GNOME/gparted/-/commit/cc7e412bc6ec2e27d049438d2a5d4cf2548cbaae

@ heikorichter
If you raise an upstream issue I'll look into it and work out what
GParted should do now.
