When encountering text nodes in an HTML document, the HTML parser needs
to run the active format reconstruction algorithm, even if it doesn't
stop to visit those text nodes. This is because the formats, which might
need reconstructing, will impact the breadcrumbs of all downstream nodes
from the text node.
In this patch, this process is triggered, which properly triggers the
active format reconstruction. It also enables the visiting of other token
types as is possible in the Tag Processor.
