Incorrect "Insufficient space" error on copy or move

Describe the bug
I am accessing a remote filesystem via SFTP. This is an NFS filesystem which is backed by BTRFS on the NFS server. When I attempt to copy or move any file it tells me "Insufficient space", despite the fact that there is over 800GB free according to df, and that these files are smaller than 1GB. I have not experienced this issue on regular BTRFS filesystems accessed over SFTP, only when NFS is involved. I have not tested with other types of filesystems.

To Reproduce
Steps to reproduce the behavior:

1. Open an SFTP connection
2. Browse to a mounted NFS filesystem (backed by BTRFS in my case)
3. Attempt to copy or move any file
4. See a toast that says "Insufficient space"

Expected behavior
The copy or move should succeed. Moves would preferably perform a rename (SSH_FXP_RENAME) rather than a copy-and-delete.
