#976 support of a dual drive floppy (4040, 8050, 8250) does not work in Vice 3.0, 3.1 but with Vice 2.4

Hi,
i am working with xpet.exe using a dos 4.0 system (e.g. CBM 8032). With Vice 2.4 and eralier i was able to use dual-drive floppy disk (e.g. CBM 4040) in the following way:

Drive-Setting->Drive 8: 4040
Attach Disk Image -> Dribe 8 (attaching disk image for drive 0 of the 4040)
Attach Disk Image -> Drive 9 (attaching disk image for drive 1 of the 4040)

(Even this is technically a workaround in reality the 4040 is attached to Unit 8 and anotherone can be attached to unit 9. I never used two dual disk drives in parallel, so i do not have practice in it,)

After attaching the two images the following commands works in Vice 2.4:

catalog  (shows the directories of both drives)
directory, cA, diR (the same as catalog)

catallog d0 (shows the directory of drive 0,  in reality drive 0, unit 8)
catalog d1 (shows the directory of drive 0,  in reality drive 0, unit 9)

load "$",8 (load directories from drive 0 and drive 1)
load "$0",8 (load directory from drive 0)
load "$1",8 (load directory from drive 1)

load "0:*",8 (loads first program from drive 0)
load "1:*",8 (loads first program from drive 1)

This works for Vice 2.4 but not for Vice 3.0 and Vice 3.1.

Is there another way to work with 4040, 8050, 8250 drives or is this a bug introduced in Vice 3.0, 3.1?
