Bug in "Clone Variant" command

FYI All Developers
I have discovered and submitted the following bug in CO 12.1.0.150 to Phase One

Regarding the Applescript command: Clone Variant additive select true
Problem: If the selection is empty, the clone is not added to the selection.

Steps to reproduce:

Open an album or a smart album. select one or more variants
Run this script:
tell application "Capture One 12"
set thevariant to (first variant whose selected is true)
deselect current document variants (variants)
clone variant thevariant with additive select
end tell
Outcome: A clone is generated. Nothing is selected.
Expected Outcome: A clone is generated, the clone is selected.
