 In some cases, it's possible to seek back into a location found inside an
 element which has been completely closed before the seek. In these cases
 the breadcrumb stack is lost, and calling get_breadcrumbs() after the seek
 will return the wrong information.

 This patch changes the seek() behavior to rewind to the start of the
 document and re-parse everything up until the sought-after bookmark
 location. This is a drastic choice but maintains the accuracy of the
 breadcrumbs. While slow, this can be later optimized in a way that
 preserves the parser state.
