My decks often have embedded Youtube iframes which are rendered as simple black boxes with `--self-contained`.

```html
<iframe width="853" height="480" src="https://www.youtube.com/embed/GzV1pNQUX5s?rel=0" frameborder="0" allowfullscreen></iframe>
```

Above becomes:

```html
<iframe width="853" height="480" data-src="data:text/html; charset=utf-8;charset=utf-8,%3C%21DOCTYPE%20html%3E%3Chtml%20lang%3D%22en......
```

I'm not sure what is actually encoded in data-src here...? It's not the video file (which would be asking a lot).

Even though I'm using the self-contained option, I still might like to click on these if network access is available.

Does `self-contained` mean network access is forbidden, or only that a best effort is made to remove dependencies. If the latter could we retain the working/original iframe?
