Subject: [PATCH] fix(tags): Dont consume a space before content tags

Content tags appeared to be "hugging" the text that preceeds them,
and as it turned out the tag regex was consuming the space, so the
final HTML actually looked like `some text<a..`, with the text node
not having the final space.

A simple oneline fix
