Text area enter with shortcut (v14)

I have added a shortcut to my default button

button.addClickShortcut(Key.ENTER)

When the focus is inside a TextArea and you press enter the button gets the shortcut action but the TextArea gets a new line entered as well. This seems wrong. It is not intuitive to a user that pressing enter would trigger the default action as well as edit the TextArea by adding a new line. Am I missing something? Is there any easy way to prevent this?

Or is there something I can do to prevent the enter from adding a new line in the TextArea, make it not respond to that key? I am happy to require a Shift + Enter for a new line.

Thanks
