Comment (by azaozz):

 The autoembed() part of the 33106.5.patch doesn't work here. It replaces
 embeddable URLs that are wrapped in a link. These should not be embedded.
 To reproduce:

 1. Paste this in the Text editor:

 {{{
 <a
 href="https://www.youtube.com/watch?v=BZL3CSUwoTc">https://www.youtube.com/watch?v=BZL3CSUwoTc</a>
 }}}

 2. Preview the post. You should see a link to that video, instead it is
 embedded (and the <a> tag is broken).

 To fix that we either need to revert to removing line breaks in
 autoembed() or do something like 33106.3.patch.
