So on our testing, this is not 100% reproducible.

I'm seeing this in the error console:
Load denied by X-Frame-Options: https://support.allizom.org/fr/kb/comment-passer-appel?mobile=1&minimal=1 does not permit framing.

This indicates that is a server side bug.

I've found something that fits all the symptoms here. In bug 997781 we added caching to the document view, but we did not cache any headers (like X-Frame-Options). Additionally, we did not take the minimal view in to account when caching things. This might have lead to some strange page views for some people on stage, though it is unlikely.

I've filed a PR to cache headers properly, and also to cache minimal views separate from the primary view. https://github.com/mythmon/kitsune/commit/1306a42aa0b41e9e4ad8fd733408696d213ac814

I've deployed this to stage, so the problem should be resolved.
