Duplicate mf2 properties

[gRegorLove]

Some properties are getting duplicated, most notably p-name because the link previews in indieweb chat concatenated them together.

Example post (archived)

u-url, dt-published, dt-updated, and the author's h-card are also duplicated, though most of those probably wouldn't interfere with link previews.

Parsed mf2:

I\u2019m not quite sure if I figured out what went wrong, but it might have to do with the #SimpleLocation plugin not wanting to work properly and display maps from Google despite the fact I have a fresh API key.
