Please trim your quotes to the parts that you are referring to.

That use of self looks incorrect!

It is certainly unwise, but not incorrect.

Usually people do `var self = this;` and I found that other places in the
code, but in ext-base.js it looks like it's being used without getting
set. Does that throw an error?

It would throw a ReferenceError exception if there was no object in the
scope chain to have such a property. After all, the `self' property of
Window objects (which would refer to its owner), and Window objects
themselves, are proprietary and host-dependent features.
