If an element is created from JS, it might have its contents modified before it is inserted into the document. In this case, we don't have a shadow tree yet and so trying to set m_text_node's text content would cause a null dereference. So let's not do that. :^) That case also means that by the time we do create the shadow tree, we have the text content already, so we can set it there. Added a test to verify that we don't crash, and that the text content appears in the textarea whether it was inserted by JS or by the HTML parser.
