Fix: Don't render Bridgy syndication inside `e-content`
As noticed when looking at the Webmention received from
https://www.jvt.me/mf2/2020/03/g1mpf/ on
https://www.jvt.me/posts/2020/03/22/at-mention-people/ the Bridgy
content is being also rendered inside the e-content
, which means it's
displaying the content twice - not ideal!
We can replace this by only wrapping the key content in e-content
.
