Videos disappearing from About me page

[Nouth 496]

I'm experiencing a minor problem with my About me page - I have several videos there, hidden in spoilers to make the page look less messy. The problem is, when I edit my About me page, the videos disappear from the spoilers, leaving but

 

tags. This only happens to videos, other content in spoilers stays unaffected.

Note : I'm also not sure if I'm posting the videos right way, I use the ,,Link" code (2nd line of icons, on right from ,,Insert/remove numbered list").

Maybe because those youtube video's have been removed?

Nope, they are not removed. One of them is the famous You're gonna go far kid with RD.

Actually, they disappear as the code. When I start to edit my About me page, they disappear from the spoilers and leave

just blank space in spoiler. It means I have to redo the spoilers, which is not fatal, but a bit annoying, and, in my opinion, worth reporting.
