An additional span inside the nodes toolbar, added by the i18n
FormattedMessage component, breaks the toolbar by changing the click
event target to the span element; because the span element doesn't
contain the "name" attribute needed to determine the appropriate action.
This patch adds a small method to lookup the closest name attribute
(either on the element or the parent elements), so both buttons with and
without a FormattedMessage of them will work.
