Time stamped videos embedding when they shouldn't?

[Wolkenkrabber]

Until recently, if we linked a YouTube video in one of our posts and we linked it to start say, one second (or one minute or three minutes etc) into a video, then the video wouldn't embed. It would open up in YouTube at the chosen timestamp and play in YouTube.
But now the video embeds here instead.

So if, for example, I link this

to play at 36:11, I would expect it to open up and play in a new tab on YouTube at 36:11. But now it embeds here in the post itself.
Have Simple Machines changed something in the software, or have the settings perhaps been changed here on the forum?
