An improvement, but there still are some extra newlines inserted after
paragraphs. Example input:
-------
Foo:
{|
|foo
|}
-------
Extra newlines are inserted after the Foo: and the foo in the table. They are
not fed as tokens or text to the tree builder, so there is likely a bug in the
html5 library or JSDom.
