I'd be wary about that.

If nothing else, what happens if someone visits the site without support for `sandbox`? You best option (not displaying it if the browser doesn't support it) breaks the site for users without JS, or that don't have support `sandbox`.

Good point. But the sandbox attribute is around 90% [1] of browsers. The number of browsers which don't support it and don't run javascript may be too low to make supporting them practical, but YMMV.
