I’m having trouble with the oneboxing of this url:

> **[After Mr. Sam](https://www.nfb.ca/film/after_mr_sam/)**
>
> This full-length documentary is the 7th and final part of Corporation, a film series about the inner workings of the Steinberg supermarket chain. This installment documents a 3-day …

It is rendered correctly in the preview but once the post is saved, the raw html of the iframe is shown instead of the onebox.

In case it matters: I am editing another users post who has posted the url as an ordinary link.

Update: it obviously didn’t matter, since the same is happening in this post.
