Cannot delete “inherent” spacer

Hi, I cannot find the way to get rid of the "invisible spacer" which is on this post, just above the video link. There is not [spacer] anywhere in the code and the code is similar to other posts which doesn't have this issue. Can you help me find how to solve this strange issue ? Thank you for your support !
