    Don't look to the next element when line nav moves us to the end
    
    When navigating in contenteditable content, moving just past a child
    element can result in our getting a caret-moved event for the end of that
    child, but not one for what is functionally the new caret position. Our
    handling for this situation is producing incorrect results when we have
    wound up at the end of an element as a consequence of line navigation.
    Therefore don't adjust the offset when navigating by line.
