Problem with YouTube when updating from 2.1.4 to 2.1.6

[jasland]

When updating from 2.1.4 to 2.1.6, there is an issue with the BBC codes when uploading a YouTube video and trying to center it or place it on the right, etc.
It turns out that if you do it like this

it doesn't show up

However, if I leave enough space between center and YouTube, it does show up. Example

                                                                         

It should now look like this

Regards

P.S.: Edit the post to show that it doesn't show up the other way, as you can see.
I've attached a screenshot.
