Masayuki Nakano 2bde324acf Bug 1501663 - part 7: HTMLEditor::GetSelectedElement() shouldn't return element node when Selection starts before the element node r=m_kato
This fixes odd case of this API.  GetSelectedElement() ignores non-element
nodes before an element node.  This must be intended to allow Selection to
start from in an element node.  However, current code allows to select starting
from previous text node.  This patch changes this behavior to stop looking
for element node if non-element node appears before an element node.
