Gnome doesn't understand btrfs - how to change main mount point?

This is the part of my /etc/fstab responsible for mounting one of my disks, formatted as btrfs without MBR or GPT:

# /dev/sdb
UUID=caa66286-a7c9-434d-afb0-6a57f817574d	/mnt/btrfs-root		btrfs	defaults,relatime					0 2
UUID=caa66286-a7c9-434d-afb0-6a57f817574d	/home/sms/Images	btrfs	defaults,relatime,autodefrag,compress=lzo,subvolid=257	0 0
UUID=caa66286-a7c9-434d-afb0-6a57f817574d	/home/sms/Pictures	btrfs	defaults,relatime,autodefrag,compress=lzo,subvolid=259	0 0
UUID=caa66286-a7c9-434d-afb0-6a57f817574d	/home/sms/Videos	btrfs	defaults,relatime,autodefrag,compress=lzo,subvolid=260	0 0
UUID=caa66286-a7c9-434d-afb0-6a57f817574d	/home/sms/Music		btrfs	defaults,relatime,autodefrag,compress=lzo,subvolid=258	0 0

What is happening is that the subvolumes are mounted as they should but the /home/sms/Images directory is understood by Gnome to be the mount point of /dev/sdb so it has the disk icon and is listed as a mount point by Gnome Disks. The thing is that lsblk returns /mnt/btrfs-root as a mount point and I want Gnome to recognise /mnt/btrfs-root as a main (or first) mount point too. How can I achieve that?
