Check if the last table element's parent node is an element when determining the foster parent element.

[Kwang Yul Seo]

According to the HTML5 spec, if the last table element in the stack of open elements has no parent, or ITS PARENT NODE IS NOT AN ELEMENT, then the foster parent element is the element before the last table element in the stack of open elements.

Changed to check if the table element's parent node is an element.

To pass fast/table/incomplete-table-in-fragment-hang.html, a special condition check was added for the fragment parsing case.
