When opening the inline reply text view by clicking on the "Reply"
button, we get a LocatedEvent to start the ripple effect from. When this
is triggered via key press, after focusing the button, the event is not
a LocatedEvent and we hit a CHECK.
This fix shows the default ripple instead if we activate via keyboard.
