This is still awaiting a pr to add snap! to the csp.

By the way, its Mediawiki page is https://www.mediawiki.org/wiki/Extension:SnapProjectEmbed.

This should be quite safe because it only accepts a user and a project. This means that a user of chrishyche and a project of Pong 1.2, it would generate something like https://snap.berkeley.edu/project?user=chrishyche&project=pong%201.2. The fact that the only user input goes inside of the "?" part makes it very safe. Since it is an iFrame, it can't change anything on the page. You can review the source code to confirm this. Using tags looks like this: <snap user="username" project="project"/>

The template is Template:Snapwikiframe

It has something to do with transcluding. I was mitigating it by adding an invisible character (‎). It's in the parentheses. Also, it might have something to do with using a template that transcludes... It may even be the template itself!

Not necessarily. I showed up with 60 recent actions. That means that there is still a problem.

Weirdly enough, after making another edit, I showed up.

Sorry about that. I accidentally dragged it.
