Binding global shortcuts to actions "extends AnAction implements DumbAware"

This is not a problem but I noticed that when a Popup is visible, then the shortcuts no longer work. 

<keyboard-shortcut keymap="$default" first-keystroke="shift alt s" />

The shortcut here for instance only works when in editor, and not when a popup is visible. 

Popup created through: 

popup = factory.createComponentPopupBuilder(panel, null)
        .setShowBorder(true)
        .setTitle(Spaces.pluginName)
        .setMovable(true)
        .setRequestFocus(true)
        
        .createPopup()
;

Is there a way to retain the shortcuts to be triggered even when a popup is active/visible? 

There is the 

factory.setKeyEventHandler( ... ) 

but how would one combine those two?
