Free space on mounted SSHFS systems

Description

I've noticed huge discrepancies between reported free space (in thunar), and actual free space on SSHFS mounted filesystems.

The space thunar show is noticibly higher than the actual free space:

$ df -h . Filesystem Size Used Avail Use% Mounted on dav@hades.barrera.io:/Series 1.9T 1.8T 74G 96% /home/hugo/videos/Shows

(Note less than 1GB free) (Yes, it's sshfs even though the username is dav)

However, the status bar when looking at /home/hugo/videos/Shows says: "5 items, Free space: 634.2GB".

About an hour ago, I also noticed that the free space was ~40GB, and thunar reported > 900GB free.

The space reported on the remote system is pretty much the same:

$ df -h . Filesystem Size Used Avail Capacity Mounted on /dev/sd2a 1.8T 1.7T 72.2G 96% /var/dav/files/Series

I understand the discrepancies when running "du" (less than 1G, less than 0.1%), but the difference between thunar and du is too much (~1000%, > 600G).

This happens for me with another 3T large sshfs mounts as well. The reported free space is proportional to the real free space, but always off by ~10x.
