ShortcutListener on tabset - there can be only one

Hello guys,

Bad behavior here with a tabset and use of ShortcutListener
Lets say we have two tabs in the tabset, each tab has a Textfield with a ShortcutListener, waiting for the key

TextField tf = new TextField();
tf.addShortcutListener(new ShortcutListener("Enter", ShortcutAction.KeyCode.ENTER, null) {
				public void handleAction(Object sender, Object target) 
	"Waouw ! An enter code !");

Only the first one will work and get the shortcut event. Other one does not react.
Same behavior in Vaadin 7 (latest) and Vaadin 8 (latest)

Can you please advise how to get out this “Highlander Rule” :wink: ?
