missing x-gvfs-hidein in mount

[ztmzzz]

After reboot, x-gvfs-hide is missing in mount. That caused hideMounts = true; useless.
mount:

/dev/nvme2n1p2 on /home/xxx/mynixos type btrfs (rw,relatime,compress=zstd:3,ssd,discard=async,space_cache=v2,subvolid=394,subvol=/persistent)

/etc/fstab have the correct content.

/persistent/home/xxx/mynixos /home/xxx/mynixos auto bind,X-fstrim.notrim,x-gvfs-hide 0 0

After login, I can run this to solve the question.

umount *
mount -a

mount:

/dev/nvme2n1p2 on /home/xxx/mynixos type btrfs (rw,relatime,compress=zstd:3,ssd,discard=async,space_cache=v2,subvolid=394,subvol=/persistent,x-gvfs-hide)

It looks like fstab ignores x-gvfs-hide, but why does mount -a get the correct result?
