ZFS sub-file systems show up in the Finder, but not in Choose File dialogs.

What steps will reproduce the problem?
1. Create a zpool. (GPT + slices)
2. Create a zfs sub-filesystem under that zpool.
3. Go to any Open or Save As or Attach dialog. One that provides a file chooser.

What is the expected output? What do you see instead?
Expected: ZFS sub-filesystems that show up in the Finder should be accessible 
in the
Instead: The ZFS sub-filesystems are only accessible as subdirectories under 
/Volumes/zpoolname/subfilesystems*

What version of the product are you using? On what operating system?
MacZFS 74.0.1
Mac OS X 10.5.8 PPC

Please provide any additional information below.
This bug is due to an inconsistency of operation between the Finder and the 
file chooser dialogs.
For consistency, either:
1) show sub-filesystems as separate volumes the same way in file chooser dialogs
OR 2) eliminate showing sub-filesystems as different volumes in the Finder 
entirely.

Thanks,
