trash -F deletes file immediately on network/shared drives

[deus0ww]

Command output:
trash: some files were not moved to trash (authentication cancelled?)

Is this expected? If it is, I'll workaround it in some other way. If not, I would really appreciate it if you fix it. The current behavior is surprising and dangerous (I already lost a few files). I would expected the command to either fail silently or with the normal Finder warning dialog.

Note that without the '-F', the command fails as expected without deleting the file. Command output:
trash: file_name: can not move to trash (-120: Directory not found)

This also happens when using a "mounted" virtual volume (such as Google Drive mounted via MountainDuck). When deleting a file with plain trash, the operation fails, but with trash -F it works although you get an error message (and the "trash" sound plays):

When trying to delete the same file from the Finder directly, there's a message that allows to cancel the operation:
