LibWeb: Stop parsing after document.write at the insertion point

Browse source 
If a call to `document.write` inserts an incomplete HTML tag, e.g.:

    document.write("<p");

we would previously continue parsing the document until we reached a
closing angle bracket. However, the spec states we should stop once we
reach the new insertion point.
