Over the past week or so, if I attempt to embed a tweet that has media with it, the media is included in the embedded tweet even if I uncheck the “Include Media” checkbox. For example, I’ve been trying to embed the following tweet this morning: https://twitter.com/harrypav/statuses/399237299679944704. I click on “More” and then “Embed Tweet”. When the tweet pops up, I uncheck “Include media” and the media disappears. I then copy and paste the HTML. When I preview my post, the media is in the embedded tweet.
I am using an up to date Chrome on MAC OS X (30.0.1599.101) and replicated on Firefox as well (24.0).
