描述

In the spec:

A browsing context that is not a nested browsing context has no parent browsing context, and is the top-level browsing context of all the browsing contexts for which it is an ancestor browsing context.

I think I can't understand what it means very well,could you give some little example?Thanks a lot.

研究方向
The issue requests a clarifying example for the term 'top level browsing context' as defined in the HTML spec. Review the spec section and existing comments (5 total) for context. A good example could contrast nested browsing contexts (like iframes) with top level ones. The fix involves adding a simple explanatory note or example to the spec documentation.
