Runkit Iframe embed do not work

Hi, i want to integrate some runkit embed on my website but the iframe fail to load.

The iframe url send to this message: Something Went Wrong

Are you still experiencing this? We were having issues a few days ago and your link works for me currently (if I copy the iframe from that request).

Hi thought it was the add blocker or Ghostery chrome extension.
But for me it do not work.
Or may be a IP problem, i deactivate Ghostery extension but it still not working.
but i can see others runkit embed from other web site like here.

But the iframe embed / Oembed do not work here (latest Chrome)

Should a javascript file have to be added with the iframe?
<iframe style = "padding: 0; margin: 0; background: transparent;" src = "" height = "40" width = "450" scrolling = "no" frameborder = "0" allowfullscreen></iframe>

Ok, it’s me, i tryed on another browser and it’s working. (Probably a Chrome Extension)
But my suggestion is to make the code part to be scrollable like Github, Gist ect.
And make the bottom always appear. (Run button)
because we can’t know the height and the result put a big blank space before we run it.
