Shortcut executed on key DOWN steals focus and blocks combination keys

While trying to create a shortcut to open CopyQ with key combination [SUPER]+V i noticed that as soon as [SUPER] is depressed the associated shortcut would execute, in my case this is to show the whiskermenu. This behavior seems incorrect and has the undesired effect of blocking my ability to use the [SUPER] key with application shortcuts.

I believe the shortcuts should fire on key release, not key down.

There is a thread I started on the Linux Mint forums that has more details: https://forums.linuxmint.com/viewtopic.php?p=2638073
