SUMMARY
I have multiple EXT4 internal drives mounted at /mnt/data/ which are pooled together using mergerfs/fuse and mounted at /mnt/storage/. A few of these folders are then bind mounted to home directories such as /Music, /Videos.

Problem is, if I trash any file over the fuse mount (whether from /mnt/storage/Videos/file or /home/user/Videos/file) the file gets moved across drives to my local home drive at ~/.local/share/Trash. I can delete from /mnt/data/drive/Videos/file and it will correctly sent to the top level trash of that drive but obviously that defeats the point of the drive pool.

This issue seems to only occur in Dolphin. Any other file manager (Thunar, PCManFM, etc.) all correctly trash the file from the drive pool.

STEPS TO REPRODUCE
1. Mount fuse filesystem pooling multiple drives (mergerfs likely)
2. Trash file from /mnt/storage drivepool
3. 

OBSERVED RESULT
File is moved to /home/user/.local/share/Trash and unable to be restored from Trash

EXPECTED RESULT
File moved to top level trash on same drive at /mnt/data/drive. Restore moves file back to original location on drive

SOFTWARE/OS VERSIONS

ADDITIONAL INFORMATION
Not seeing any errors but there's definitely a huge delay (up to a minute) trying to trash any kind larger file (~1GB). Drivepool is not using any existing path create policies.

My mount settings from /etc/fstab:
