Sorry about that. Caja is being maintained in a few people's spare time,
mostly mine, and I've been busy with other work and scheduling issues. So,
basically all my fault.

What's broken in the playground is ES5/3 mode (which nobody should be
using) and loading the examples. If you type/paste your content it should
load fine.

The playground is due for a replacement, really — it has lots of code and
UI that is left-over from ES5/3 mode and doesn't really make sense. There's
a lighter-weight version of the same idea in the source tree called
“generic-host-page”, but it is a little too minimal.

In the typical pattern of use, no. However, you can, instead of providing a
HTML element as the container, provide an <iframe>'s document. If you do,
then it will behave as iframes usually do, including not sharing styles.
