 Hi all,

 Banging my head against something, hoping you guys can help.

 We upgraded from 4.7.2 to 4.8.2, and immediately saw an uptick in
 update_post_meta calls. Took us a while to track it down, but we narrowed
 it to oEmbeds. This is a weird one.

 Multiple posts have no oEmbeds but when I query them in the DB, they have
 20-80 oEmbeds associated to the post_id in the postmeta table. Other
 posts' oEmbeds are somehow being associated with these posts on mass.

 Well there's our uptick in update_post_meta calls!

 I've been looking at class-wp-embed.php:143 shortcode() and I can't for
 the life of me figure out why this is happening. I've also looked at all
 the diff of the relevant files from 4.7.2 to 4.8.2. I'm clearly missing
 something.

 I haven't been able to isolate when or why it does the update_post_meta to
 the wrong post_id.

 Anyone have any thoughts?
